Egg "A" is thrown at a brick wall and splatters. Egg "B" is thrown at a hanging bed sheet and comes to a rest in tact (without breaking). Which of the following statements is true.

: Egg "A" experiences a greater force due to decreased time of impact.

Egg "B" experiences a great impulse than Egg "A".

Egg "A" experiences a greater impulse than Egg "B".

Egg "B" experiences a greater force due to an increased time of impact.

Egg "A" experiences a greater impulse and force than Egg "B".

An engineer is designing a state of the art rollercoaster, and uses the conservation of energy to calculate the velocity at the bottom the first drop on the rollercoaster. Her calculations for the velocity at the bottom of the drop predict a velocity of 20 m/s. Which of the following statements is true?

Question 18 options:

	The velocity will be less than 20 m/s due to some of the energy being lost to friction, sound, and vibrations of the coaster and track.
	The velocity will be exactly 20 m/s because there are no other factors that can affect the energy transferring potential energy to kinetic energy.
	The velocity will be greater than 20 m/s due to the increased force and weight as the coaster moves down the incline.

Will N. Andable and Ben Pumpiniron are carrying similar boxes up the stairs. Will carries the box up in half the time that Ben does. Which of the following is true?

Question 16 options:

	Ben and Will utilize the same work and power
	Will utilizes twice as much power as Ben
	Will does twice as much work as Ben
	Ben does twice as much work as Will
	Ben utilizes twice as much power as Will
