Answer:

The value is  [tex]t = 18.6 s[/tex]

Explanation:

From the question we are told that

     The average acceleration of the bicycle is [tex]v = -0.44 \ m/s^2[/tex]

      The initial forward velocity is  [tex]u = 8.2 \ m/s[/tex]

Generally from kinematic equations we have that

      [tex]v = u + at[/tex]

Here v is the final velocity of the bicycle and the value is v = 0 m/s

So

      [tex]0 = 8.2 + (-0.44)t[/tex]

=>    t = 18.6 s

Answer:

C- 60 N to the left

Explanation:

there is a 60n arrow to the left of the box

Answer:if 1 m = 100 cm then there should be 200 cm in m^2

Explanation:

Given that,

Weight of a car, W = 12,000 N

It is parked on a 36° slope.

To find,

The acceleration of the car.

Solution,

Let m be the mass of the car. Using formula for weight of an object.

W = mg

[tex]m=\dfrac{12000}{9.8}\\\\=1224.48\ kg[/tex]

Let a be the acceleration of the car. Using second law of motion as follows :

[tex]a=\dfrac{F_{\text{parallel}}}{m}\\\\=\dfrac{F\sin\theta}{m}\\\\=\dfrac{12000\times \sin(36)}{1224.48}\\\\=5.76\ m/s^2[/tex]

So, the acceleration of the car is [tex]5.76\ m/s^2[/tex].

Answer:

Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,

when the distance between the two object is increased the gravitational force decreases by its square,

and when the mass an object increases the gravitational force also increases,

therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.

Answer:

Black bodies are good absorber of light waves from the sun, while shining surfaces are good reflector of the light waves.

Explanation:

Generally, a black surface or material tends to absorb light waves while under the sun, while a shiny surface is a good reflector of the waves. This is because the black material is a good absorber, and also a good emitter.

The shiny necklace can only absorb little light waves from the sun, thus it reflects most of the light waves. The reflection is the reason for the small circles of light seen around the yard.

However, when in a cool environment the black shirt would cools faster (good emitter) than the shiny necklace.

Answer:

momentum

Explanation:

The net impulse delivered to an object always causes a change in the object's momentum. Hence, option (B) is correct.

The given problem is based on the concept of net impulse. The magnitude of force acting on any object for very short interval of time is known as impulse. In the given problem, the transfer of impulse can be explained by the impulse - momentum theorem.

[tex]F \times t = \Delta P\\\\I= \Delta P[/tex]

Here, I is the impulse.

Thus, we can conclude that the net impulse delivered to an object always causes a change in the object's momentum. Hence, option (B) is correct.

Electrical energy

Explanation:

electrical energy Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

12.00 min = 0.2 hr

8.00 min = 0.15 hr

Total distance:

(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) + (20.0 km/hr) (0.2 hr)

= 8.25 km

Average speed:

(10.0 km/hr + 15.0 km/hr + 20.0 km/hr) / 3

= 15 km/hr

Change in position:

(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) - (20.0 km/hr) (0.2 hr)

= 0.25 km

Average velocity:

(10.0 km/hr + 15.0 km/hr - 20.0 km/hr) / 3

≈ 1.67 m/s

Answer:

The impulse transferred to the nail is 0.01 kg*m/s.

Explanation:

The impulse (J) transferred to the nail can be found using the following equation:

[tex] J = \Delta p = p_{f} - p_{i} [/tex]

Where:                                                                

[tex]p_{f}[/tex]: is the final momentum

[tex]p_{i}[/tex]: is the initial momentum

The initial momentum is given by:

[tex] p_{i} = m_{1}v_{1_{i}} + m_{2}v_{2_{i}} [/tex]

Where 1 is for the hammer and 2 is for the nail.

Since the hammer is moving down (in the negative direction):

[tex]v_{1_{i}} = -10 m/s [/tex]

And because the nail is not moving:

[tex]v_{2_{i}}= 0[/tex]                      

[tex] p_{i} = m_{1}v_{1_{i}} = 0.25 kg*(-10 m/s) = -2.5 kg*m/s [/tex]

Now, the final momentum can be found taking into account that the hammer remains in contact with the nail during and after the blow:

[tex] p_{f} = m_{1}v_{1_{f}} + m_{2}v_{2_{f}} [/tex]

Since the hammer and the nail are moving in the negative direction:

[tex]v_{1_{f}}[/tex] = [tex]v_{2_{f}}[/tex] = -9.7 m/s

[tex] p_{f} = -9.7 m/s(7 \cdot 10^{-3} kg + 0.25 kg) = -2.49 kg*m/s [/tex]

Finally, the impulse is:

[tex] J = p_{f} - p_{i} = - 2.49 kg*m/s + 2.50 kg*m/s = 0.01 kg*m/s [/tex]

Therefore, the impulse transferred to the nail is 0.01 kg*m/s.

Given that,

Mass of a frog, m = 0.5 kg

The frog leaps pushing off of the rock with an acceleration of 5.0 m/s².

To find,

The magnitude of the net force exerted on the frog as it leaps.

Solution,

Let the net force exerted on the frog is given by the formula as follows :

F = ma

Putting the values of m and a to find F as follows :

F = 0.5 kg × 5 m/s²

F = 2.5 N

So, the magnitude of net force is 2.5 N.

The magnitude of the net force exerted on the frog as it leaps is 2.5 Newtons.

Hence, Option a) 2.5N is the correct answer.

Given the data in the question;

Force Exerted; [tex]F = ?[/tex]

To determine the magnitude of the net force exerted on the frog as it leaps, we the expression from the Newton's Second law of motion:

[tex]F = m * a[/tex]

Where m is mass and a is acceleration

We substitute our given values into the equation

[tex]F = 0.5kg * 5.0m/s^2\\\\F = 2.5kgm/s^2\\\\F= 2.5N[/tex]

The magnitude of the net force exerted on the frog as it leaps is 2.5 Newtons.

Hence, Option a) 2.5N is the correct answer.
