A car is moving along a straight highway. The car hits from behind a heavy truck moving in the same direction. After the collision, the truck and the car do not separate. During the collision, which vehicle experiences greater impulsive force?

• the car

• the truck

• both vehicle experience equal impulsive force

• not enough information to answer

A tennis ball is dropped from a 1.0 m height, bounces off the ground, and rises to 0.85 m. What kind of collision occurred between the ball and the ground?

• Elastic collision

• Inelastic collision

• Perfectly inelastic collision

• Not enough information to answer

One example of an object in equilibrium is:

• a 2400 kg car moving North at a speed of 90 km h^-1.

• a ball thrown upward that reaches its maximum height.

• a steel ball falling from the top of the Pisa tower.

• a swinging pendulum hanging from the ceiling.

A massive block is being pulled along a horizontal frictionless surface by a constant horizontal force. The block must be:

• Continuously changing direction

• Moving at constant velocity

• Moving with a constant non-zero acceleration

• Moving with continuously increasing acceleration

A block is acted upon by two forces of equal magnitude and opposite directions. Therefore, one can conclude that:

• the velocity of the block must be zero.

• the velocity of the block must not be zero.

• the acceleration of the block must be zero.

• the block must be slowing down.

Which of the following is the best example of work being done?

• Sitting in a box

• Pushing a stationary box

• Lifting a box

• Holding a box
