A block of mass m 0.659 kg is fastened to an unstrained horizontal spring whose spring constant is k 84,8 N/m. The block is given a displacement of +0.152 m, where the sign indicates that the displacement is along the +x axis, and then released from rest. (a) What is the force (with sign) that the spring exerts on the block just before the block is released? (b) Find the angular frequency w of the resulting oscillatory motion. (c) What is the maximum speed of the block? (d) Determine the magnitude of the maximum acceleration of the block.

(a):
force exerted by spring on the block = kx = 84.4*0.152 = 12.8288 N
(b):
omega = sqrt(k/m) = sqrt(84.8/0.659) = 11.3437 radians/s
(c):
max speed of the block = amplitude of oscillation * angular velocity(omega) = 0.152*11.3437= 1.7242 m/s
(d):
max acceleration = amplitude* omega^2 = 0.152* (11.3437)^2 = 19.5593 m/s^2
