A 0.40kg object is attached to a spring constant 160N/m so that the object is allowed to move on a horizontal frictionless surface. The object is released from rest when the sprin g is compressed 0.15m find:
a) the force on the object and b) its acceleration at this instant.
do u know the formula F=kx here F=force exerted on object by spring=? k=spring constant=160N x=displacement of spring=0.15m now tell me the result u got
