A child and sled with a combined mass of 50.0 kg slide down a frictionless slope. if the sled starts from rest and has a speed of 4.00 m/s at the bottom, what is the height of the hill? m

A turtle crawls along a straight line, which we will call the x-axis with the positive direction to the right. The equation for the turtle's position as a function of time is x (t) = 50.0cm + (2.00cm/s) t - (0.0625cm/s2) t2.

The force exerted by expanding gases is what propels a shell out of a gun barrel. Suppose a force that has an average magnitude F propels the shell so that it has a speed v at the instant it reaches the end of the barrel.
