Space-shuttle astronauts experience accelerations of about 35 m/s2 during takeoff. What force does a 75 kg astronaut experience during an acceleration of this magnitude?

Answers

Answer 1

Answer:

The answer is 2625 N

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 75 × 35

We have the final answer as

2625 N

Two balls have the same mass. One ball moving along the positive x–axis and the other ball moving along the positive y–axis undergo perfectly inelastic collision. What can you say about the motion of the balls after the collision?

A.
The balls stick and move together.
B.
The balls separate immediately.
C.
The first ball stops while the other ball starts moving.
D.
The two balls travel off in opposite directions, 180° apart.

Answers

Answer:

A. The balls stick and move together.

Explanation:

When a bodies undergo perfectly inelastic collision, the two bodies stick together after the collision and begins to move.

In this collision, kinetic energy is not conserved. For perfectly elastic collision, the two bodies conserve kinetic energy and begin to move apart.

Kinetic energy is not conserved because some of the energy gets converted into other forms of energy.

In lab you submerge 100 g of iron nails at 40 0C in 100 g of water at 20 0 C. Specific heat of iron is 0.12 cal/g∙0C. Equate the heat gained by water to the heat lost by nails and show that the final temperature of water becomes 22.1 0C.

Answers

Let T be the final temperature of water and nails (iron).

Given that the initial temperature of 100 g nails, [tex]T_{1F}=40^{\circ}C[/tex].

Specific heat of the iron, [tex]C_F=0.12 cal/g^{\circ}C[/tex].

So, the heat lost by nails [tex]= mC_F(T_{1F}-T}[/tex]

[tex]=100\times 0.12 \times (40-T)\cdots(i)[/tex]

The initial temperature of 100 g water, [tex]T_{1w}=20^{\circ}C.[/tex]

Specific heat of water, [tex]C_w=1 cal/g^{\circ}C[/tex]

So, the heat gained by water [tex]= mC_w(T-T_{1w}}[/tex]

[tex]=100\times 1 \times (T-20)\cdots(ii)[/tex]

As the exergy is conserved, so

the heat lost by the nails = the heat gained by the water

From equation (i) and (ii), we have

[tex]100\times 0.12 \times (40-T)=100(T-20)[/tex]

[tex]\Rightarrow 0.12(40-T)=T-20[/tex]

[tex]\Rightarrow 0.12\times 40 -120T=T-20[/tex]

[tex]\Rightarrow 0.12T+T=4.8+20[/tex]

[tex]\Rightarrow 1.12T=24.8[/tex]

[tex]\Rightarrow T=24.8/1.12= 22.1^{\circ}C[/tex]

Hence, the final temperature of both, iron nails as well as water, become [tex]22.1^{\circ}C[/tex].

A car increases velocity from 30 m/s to 60 m/s in 4 seconds. Calculate the average acceleration of the car over this time.
0.3 m/s2
7.5 m/s2
0.6 m/s2
4.8 m/s2

Answers

Answer:

B.7.5m/s2

Explanation:

average acceleration=change invelocity/time taken

a=(60-30)/4

=7.5m/s2

The average acceleration of the car 7.5 m/s²

The parameters given in the question are;

initial velocity= 30 m/s

final velocity= 60 m/s

time= 4 seconds

The formula that can be used to calculate the average acceleration is

= final velocity-initial velocity/time

= 60-30/2

= 30/2

= 7.5

Hence the average acceleration is 7.5 m/s²

Math Practice: Cart A loaded with blocks (600g) moving left at 0.7m/s hits stationary cart B (200g).
After the collision, both carts move left, Cart A at speed 0.27m/s.

What is the velocity of cart B after the collision? Show your work.

Answers

Answer:

The velocity of cart B after the collision is 1.29 m/s.

Explanation:

We can find the velocity of cart B by conservation of linear momentum:

[tex] p_{i} = p_{f} [/tex]

[tex] m_{A}v_{A_{i}} + m_{B}v_{B_{i}} = m_{A}v_{A_{f}} + m_{B}v_{B_{f}} [/tex]

Where:

[tex]m_{A}[/tex] is the mass of cart A = 600 g = 0.6 kg            

[tex]m_{B}[/tex] is the mass of cart B = 200 g = 0.2 kg

[tex]v_{A_{i}}[/tex] is the inital velocity of cart A = 0.7 m/s

[tex]v_{A_{f}}[/tex] is the final velocity of cart A = 0.27 m/s

[tex]v_{B_{i}}[/tex] is the initial velocity of cart B = 0

[tex]v_{B_{f}}[/tex] is the final velocity of cart B =?

Taking the left direction as the positive horizontal direction:

[tex] 0.6 kg*0.7 m/s + 0 = 0.6 kg*0.27 m/s + 0.2 kg*v_{B_{f}} [/tex]

[tex] v_{B_{f}} = 1.29 m/s [/tex]

                       

Therefore, the velocity of cart B after the collision is 1.29 m/s.

A rock falls off a cliff that is 82 m high. How fast is the rock moving when it hits the ground?

Answers

Answer:

40.1m/s

Explanation:

This is a kinematics problem

x = 82m

a = -9.8m/s^2

v(initial) = 0

Find: v(final)

Using kinematics equation:

vf^2 = vi^2 + 2a(delta)x

vf^2 = 0 + 2*(-9.8)*(82)

vf = sqrt(1607.2) = 40.09m/s

The is traveling with a velocity of 40.1m/s when it hits the ground.

how is force spread over long and short durations of time?

Answers

I think you're having trouble with it only because of how you're trying to look at it.

Don't try to imagine "spreading force" over time. Just think about how long the force lasts !

Like . . .

If you push your doll stroller for 5 seconds, you'll get it up to a certain speed.

Next time, if you push it again with the same force, but you keep pushing for TEN seconds, you'll get it up to a faster speed.

Technically:

(force • time) = impulse.

You gave it more impulse the second time, so it got more momentum from you.

car.

Answers

Explanation:

Given parameters:

Mass of the car = 1500kg

Force applied  = 1000N

Acceleration  = 0.67m/s²

Unknown:

Proof that the acceleration will result from the applied force on the car

Solution:

According to newton's second law of motion,

       Force  = mass x acceleration

 So;

 Acceleration  = [tex]\frac{Force }{mass}[/tex]

Now insert the parameters and solve;

 Acceleration = [tex]\frac{1000}{1500}[/tex]   = 0.67m/s²

Emily rides on a horizontal rotating platform of radius r at an amusement park
and moves at a linear velocity, vt = 1 m/s, one third the way from the center to the
outer edge, and a rotational velocity of 2 RPM. How much would her linear and
rotational velocities be if she moves to the outer edge?

Answers

Answer:

Her linear velocity on the outer edge is 3 m/s

Her rotational velocity, is constant at 2 RPM

Explanation:

The given parameters are;

The radius of the rotating platform = r

The linear velocity  v(t) = 1 m/s

The position Emily is riding = 1/3 the distance from the center

The rotational velocity = 2 RPM = 2 Revolutions per minute

The formula for angular velocity, ω is given as follows;

ω = θ/t

Where;

θ = The angle rotated

t = The time taken for the rotation

Given that the rotational velocity = 2 RPM

1 revolution = 2·π radians

The angular velocity, ω = 2×π×(2 RPM) = 4·π rad/min = 4·π/60 rad/seconds

ω = 4·π/60 rad/seconds

The linear velocity, v = r₁×θ/t = r₁×ω

Where;

r₁ = 1/3 × r

v = 1 m/s = 1/3 × r  × 4·π/60 rad/seconds

∴ r = 1/(1/3 × 4·π/60) = 45/π meters

r = 45/π meters

Therefore her linear velocity, v₂ and her rotational velocity if she moves to the outer edge will be given as follows;

v₂ = r × ω = 45/π × 4·π/60 = 3 m/s

Her linear velocity on the outer edge, v₂ = 3 m/s

Her rotational velocity, remains at 2 RPM.
