A ball is released from the top of a 2-meter long ramp and rolls down with a uniform acceleration of 3 m/s^2. a. How fast is the ball moving when it reaches the bottom of the ramp?
b. How long does it take to roll down the ramp?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

Ahockey puck sliding along frictionless ice with speed v to the right collides with a horizontal spring and compresses it by 3.0 cm before coming to a momentary stop.
