A 0.055-kg egg falls off a table that is 1.2 m high and lands on a tile floor. Part A What is the impulse delivered to the egg by the floor? Assume that the positive direction is upward. Express your answer with the appropriate units. Part B The egg lands on its side, and at the instant of impact the part of the shell farthest from the floor is 40 mm above the floor. The collision continues until the center of mass is on the floor. Estimate the time interval over which the collision lasts, assuming that the speed of the center of mass of the egg drops to zero linearly in time. Express your answer with the appropriate units. Part C What is the average force exerted by the floor on the egg? Assume that the positive direction is upward. Express your answer with the appropriate units. Part D If the floor were carpeted, the collision time interval might be extended by as much as a factor of four as the carpet "gives" under the egg. What would the average force exerted on the egg be then? Assume that the positive direction is upward. Express your answer with the appropriate units.

Question

A 0.055-kg egg falls off a table that is 1.2 m high and lands on a tile floor.  

Part A
What is the impulse delivered to the egg by the floor? Assume that the positive direction is upward.
Express your answer with the appropriate units.

Part B

The egg lands on its side, and at the instant of impact the part of the shell farthest from the floor is 40 mm above the floor. The collision continues until the center of mass is on the floor. Estimate the time interval over which the collision lasts, assuming that the speed of the center of mass of the egg drops to zero linearly in time.
Express your answer with the appropriate units.
 

Part C

What is the average force exerted by the floor on the egg? Assume that the positive direction is upward.
 
Express your answer with the appropriate units.
 

Part D

If the floor were carpeted, the collision time interval might be extended by as much as a factor of four as the carpet "gives" under the egg. What would the average force exerted on the egg be then? Assume that the positive direction is upward.
Express your answer with the appropriate units.
