A long cylinder of diameter 20 cm is closed
at one end. A piston is located at the other
end of the cylinder, as shown in the
diagram. The piston is attached to a spring
with the spring constant 5.0 * 10' N/m.

The cylinder is placed in water at 50 m
depth. What is the displacement of the
piston? Given: density of water = 1.0 x 10
kg/m and 9 = 9.8 m/s?

Ajogger accelerates from rest to 4.86 m/s in 2.43 s. a car accelerates from 20.6 to 32.7 m/s also in 2.43 s. (a) find the magnitude of the acceleration of the jogger. (b) determine the magnitude of the acceleration of the car. (c) how much further does the car travel than the jogger during the 2.43 s?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.
