An ideal spring is used to fire a 25.0 g pellet horizontally. The spring has a spring constant of k = 125 N/m
and is initially compressed by x = 9.00 cm from its equilibrium position. What is the speed of the pellet as it
leaves the spring? This is a positive number. Give your answer in m/s.
An 2.1 kg object is launched down a frictionless ramp at 7.2 m/s towards a spring connected to the bottom end of the ramp. The ramp is 44.8 m long and is angled at 48.4o above the horizontal. The spring constant for the spring is 1770 N/m. By how much is the spring compressed by the object? Round final answers to 2 decimal places.
A 200 g block on a frictionless surface is pushed
against a spring with spring constant 500 N/m,
compressing the spring by 2.0 cm. When the block
is released, at what speed does it shoot away from
the spring?
