1. A 0.28 kg mass is attached to a light spring with a force constant of 32.9 N/m and set into oscillation on a horizontal frictionless surface. If the spring is stretched 5.0 cm and released from rest, determine the following.(a) maximum speed of the oscillating mass m/s (b) speed of the oscillating mass when the spring is compressed 1.5 cm m/s (c) speed of the oscillating mass as it passes the point 1.5 cm from the equilibrium position m/s (d) value of x at which the speed of the oscillating mass is equal to one-half the maximum value m

2. A 0.40-kg mass is attached to a spring with a force constant of

k = 387 N/m,

and the mass-spring system is set into oscillation with an amplitude of

A = 1.7 cm.

Determine the following.(a) mechanical energy of the system J (b) maximum speed of the oscillating mass m/s (c) magnitude of the maximum acceleration of the oscillating mass m/s²

3. A mass attached to the end of a spring is oscillating with a period of 2.25 s on a horizontal frictionless surface. The mass was released from rest at

t = 0

from the position

x = 0.0640 m.

(a) Determine the location of the mass at t = 5.92 s?

_____ m (b) Determine if the mass is moving in the positive or negative x direction at t = 5.92 s?

positive x direction or negative x direction
