Calculate the mass of an object if it took 20 N of force to rotate it in a circle with a radius of 2 meters with a velocity of 4 m/s

4.1 kg

3.6 kg

2.5 kg

1.8 kg

Why do objects experience centripetal acceleration?

Because they are speeding up as they move in a circle

Because they are constantly changing direction and the net change is directed inward

Because they are constantly changing both speed and direction

Because when you have 100 people pedaling, you can speed up more easily.

At the instant shown in the diagram, the car's centripetal acceleration is directed-

toward E

toward N

toward W

clockwise

The velocity is always _____ to the line of a circle.

outwards

towards the center

tangent

faster

If the radius of the string is .3 meters long and the stopper makes 5 revolutions per second, what is the speed of the stopper? (Hint: C=2πr)

9.4 m/s

6.8 m/s

11.7 m/s

3.5 m/s

If a ball is swinging at the end of a rope and the rope is suddenly cut, assuming there is no gravity, what best describes the path it will take?

It will fly in a straight line forward from where it was cut

It will fly in a curved line away from the circle

It will fly inward toward the circle

A toy train moves in a circular track with a velocity of 2.2 m/s, the axis of rotation is 1.8 m. What is its centripetal acceleration?

1.47 m/s²

What is the tangential velocity if the centripetal force is 150 N when a 3 kg toy plane flies in a 2 m radius circle?

10 m/s

100 m/s

225 m/s

F/3

F/2

F/6

F/9

14.

Force of gravity is inversely proportional to

Doubles

Quadruples

Cut in Half

4x Smaller

16.

What is the Universal law of gravitation equation?

G=F ⋅ m⋅m2/r²

F=G ⋅ m⋅m₂/(r)²

Increases

Decreases

Remains the same

Cannot be determined

19.
