1. In 0.720 s, a 6.95-kg block is pulled through a distance of 3.70 m on a frictionless horizontal surface, starting from rest. The block has a constant acceleration and is pulled by means of a horizontal spring that is attached to the block. The spring constant of the spring is 460 N/m. By how much does the spring stretch in kg?
2. An object attached to a horizontal spring is oscillating back
and forth along a frictionless surface. The maximum speed of the
object is 1.37 m/s, and its maximum acceleration is 6.98
m/s2. How much time elapses between an instant when the
object's speed is at a maximum and the next instant when its
acceleration is at a maximum?

A 3.70 kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 19.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations (a) Find the force constant of the spring, N/m (b) Find the frequency of the oscillations Hz...
