A 4.0 kg object is moving with a speed of 2.0 m/s. A 1.0 kg object is moving with a speed of 4.0 m/s. Both objects encounter the same constant braking force and are brought to rest. Which object travels the greater distance before stopping?

1) the 4.0 kg object

2) the 10 kg object

3) Both objects travel the same distance.

4) It cannot be determined from the information given

Part A
A cart on an air track is moving at 0.5m/s when the air is suddenly turned off. The cart comes to rest in 1m. The experiment is repeated with the cart moving at 1 m/s when the air is turned off. How far does the cart travel before coming to rest?
a) 1 m
b) 2 m
c) 3 m
d) 4 m
Part B
A 4 kg mass with a speed of 2m/s and a 2kg mass with a speed of 4m/s are gliding over a horizontal frictionless surface. Both objects encounter the same horizontal force, which opposes their motion, and are brought to rest. Which statement best describes their stopping distance?
a) the 4 kg mass travels twice as far as the 2 kg mass before stopping.
b) the 2 kg mass travels twice as far as the 4 kg mass before stopping.
c) both masses have the same stopping distance.
d) the 2 kg mass travels farther, but not necessarily twice as far.

A 5.0 kg object moving along a straight line trajectory with aspeed of 4.0 m/s collides head-on with a 10.0 kg object movingtoward it along the same straight line with a speed of 3.0 m/s. The10.0 kg object stops dead after the collision. Consider as positivethe direction of motion of the 5.0 kg along the straight lineobject before the collision.

(A) What is the linear momentum of the 5.0 kg object before thecollision?

(B) What is the linear momentum of the 10.0 kg object before thecollision?

(C) What is the velocity of the 5.0 kg object after the collision?

A 2-kg object moving to the right with a speed of 4 m/s makes a head-on, elastic collision with a 1-kg object that is initially at rest. The velocity of the 1-kg object after the collision is

(a)greater than 4 m/s

(b) less than 4 m/s 

(c) equal to 4 m/s

(d) zero

(e) impossible to say based on the information provided
