Komila knows that an egg breaks if it falls onto a concrete floor from a height of 0.4 m. She finds, however, that an egg does not break when it falls from the same height onto a floor that is covered with a 2.0-cm-thick carpet.
Fill in the blanks with appropriate words given below:

carpet, spread, larger, smaller, egg

When the egg hits the , it stops over a longer distance so its stopping time interval is , resulting in a acceleration. Thus, a force must have been exerted by the on the egg. In addition, as the egg compresses the carpet, the force is over a small area of the shell.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
