A sock stuck to the side of a clothes-dryer barrel has a centripetal acceleration of
28m/s?. If the dryer barrel has a radius of 27.5cm, what is the tangential speed of the
sock?
Answer:
Tangential speed, V = 2.78 m/s.
Explanation:
Given the following data;
Centripetal acceleration = 28m/s²
Radius = 27.5cm to meters = 27.5/100 = 0.275 meters
To find the tangential speed;
Centripetal acceleration = V²/r
Substituting into the formula, we have;
28 = V²/0.275
V² = 28 * 0.275
V² = 7.7
Taking the square root of both sides, we have;
Tangential speed, V = 2.78 m/s.
The tangential speed of the sock will be 7.7 m/sec².Tangential speed is as the linear speed of any object travelling along a circular route.
What is tangential speed ?Tangential speed is defined as the linear speed of any item travelling along a circular route.
A point on the outside edge of a turntable travels further in one complete rotation than a point towards the center.
The given data in he problem is;
a is the centripetal acceleration =28m/s?
r is the radius of 27.5cm
v is the tangential speed of the sock=?
[tex]\rm a= \frac{v^2}{r} \\\\ \rm v= \sqrt{ar} \\\\ \rm v= \sqrt{28 \times 0.275 } \\\\ \rm v=7.7 \ m/sec^2[/tex]
Hence the tangential speed of the sock will be 7.7 m/sec².

Calculate the decrease in gravitational potential energy of the ball as it moves down through the 0.90m the mass of the ball is 0.60kg
Answer:
G.P.E = 5.292 Joules
Explanation:
Given the following data;
Mass = 0.6 kg
Height = 0.9 m
To find the gravitational potential energy;
Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
Mathematically, potential energy is given by the formula;
[tex] G.P.E = mgh[/tex]
Where,
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
But we know that acceleration due to gravity is equal to 9.8m/s²
G.P.E = 0.6*9.8*0.9
G.P.E = 5.292 Joules
Two rocks are at the top of a building. Rock 1 is dropped from rest while Rock 2 is thrown horizontaly at a velocity of 5 ms.
What is the magnitude of the horizontal acceleration of rock 2?>
Omis 2
2 ms 2
5 ms 2
10 mis2
Answer:
I'm pretty sure the answer is 0 m/s²
Explanation:
The horizontal velocity of the second rock is 5 m/s, so if we pretend air resistance doesn't exist, it will maintain that horizontal velocity, meaning that there is no horizontal acceleration.

Which pair of graphs represent the correct relationship between position x and velocity v of a moving object?
Well we can't see (B) in your picture, so we can't comment on it.
But ' D ' depicts a correct relationship between a position and a speed.
(And C doesn't.)
Answer:
We can't see B, but D would be correct while C would not be.
Explanation:
C shows an object not moving with the position graph and shows the object decelerating in the velocity graph.
D shows the object moving at a constant speed in a positive direction and the velocity graph shows a constant velocity.
Which of these is an example of work being done on an object a. Holding a heavy piece of wood at a construction site. b. Trying to push a car that doesn't move out of deep snow. c. Pushing a child on a swing. d. Holding a door shut on a windy day so it doesn't blow open.
Answer:
I would say the best choice, would be Choice C.
For all of these scenarios a force is being applied to displace an object. But the displacement occur in the case of trying to push a car and pushing a child on a swing. Thus, options b and c are correct.
What is work done?Work done in physics is the dot product of force and displacement. Therefore, every work done is associated with a force but not all force result in work done. Those force, which result in a displacement will do work done.
Holding a heavy piece of wood does not make a displacement in the object. Similarly, when we hold the door to stop we just apply a force and not displacing the door. In both cases work done is zero.
When we push a car to make it move and any movement from the side of the car result in a work done. Similarly in when we push a child in a swing we make the swing move a distance by applying force. Thus work is being done on the object.

A horizontal force of 164 N is applied to move a 55 kg television set across a 9 m level surface. What is the work done by the force on the television set?
Answer:
Workdone = 1476 Nm
Explanation:
Given the following data;
Force = 164 N
Mass = 55kg
Distance = 9 m
To find the work done;
Workdone = force * distance
Workdone = 164 * 9
Workdone = 1476 Nm
Therefore, the work done by the force on the television set is 1476 Nm.

Which of the following claims is supported by the data?
A. Gravitational force are proportional to the masses of the two objects.
B. Gravitational forces are strongest between objects with identical masses.
C. Gravitational forces are weakest when one object is more massive than the other.
Answer:
Explanation: the table shows during an experiment
Gravitational forces are strongest between objects with identical masses, claims are supported by the data. Option B is correct.
What is Newton's law of gravitation?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
When mass increases and distance reduces, gravity rises. Gravity also lowers when the distance between two points grows and the mass decreases.
From the table, it is observed that gravitational forces are strongest between objects with identical masses, claims are supported by the data.
Hence, option B is correct.
