A spring with a constant of #6 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #5 kg# and speed of #9 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
By conservation of mechanical energy when the spring is compressed fully after collision
PE gained by the spring = Initial KE of the colliding object
m = mass=5kg
v=velocity of the object=
k = force constant=
x= compression of spring=?
