Question:
A block, whose mass is kg is attached to a spring with a force constant of Nm The block rests upon a frictionless, horizontal surface
A block labeled m is attached to the right end of a horizontal spring, and the left end of the spring is attached to a wall. The spring is stretched horizontally such that the block is displaced by a distance A to the right of its equilibrium position.
The block is pulled to the right a distance A m from its equilibrium position the vertical dashed line and held motionless. The block is then released from rest.
a
At the instant of release, what is the magnitude of the spring force in N acting upon the block?
b
At that very instant, what is the magnitude of the block's acceleration in ms
