Physics
A thin uniform rod has mass M = 0.5 kg and length L= 0.49 m. It has a pivot at one end and is at rest on a compressed spring as shown in (A). The rod is released from an angle θ1= 55.0o, and moves through its horizontal position at (B) and up to (C) where it stops with &#...

Physics
A spring is mounted horizontally. A crate which has a mass of 8.5kg is pressed against the spring with a force of 350N. As a result the spring is compressed a distance of 82.0cm. The mass is then released and is allowed to slide along the horizontal, frictionless surface. What...

Physics
A spring with k=40.0 N/m is at the base of a frictionless 30.0 degree inclined plane. A 0.50-kg object is pressed against the spring, compressing it 0.20m from its equilibrium position. The object is then released. If the object is not attatched to the spring, how far up the ...

Physics, spring force
To compute work done by the spring force, calculate the area of a: a)rectangle b)circle c)triangle The spring force changes as a function distance, so triangle if on a F vs x plot

physics please help
suppose a cart of mass m = 969 g is initial moving at speed v0 = 5.17 m/s. It strikes a spring attached to a fixed wall, comes to a stop, and bounces back at speed vf = 4.48 m/s. Assume the track is frictionless. a) Find the magnitude of the impulse exerted by the spring on ...
