Question

1 and 2 please The first question says 'is given by' ... harmonic motion is given 1. The position of a 0.64-kg mass undergoing simple x -(0.160 m) cos (16rt). What is its frequency of oscillation? B. 32 Hz D. 8.0 Hz A. 100 Hz C. 16 Hz nic motion. When the mass is at its rom the equilibrium position, which of the following statements 2. A mass-spring system executes simple harmonic motion. maximum distance f about it are true A) Its acceleration is zero. B) Its speed is zero. C) Its elastic potential energy is zero. D) Its kinetic energy is a maximum. E) Its total mechanical energy is zero.

Explanation / Answer

X=(0.160)cos(16t)

X=(Amplitude) cos(wt)

f=w/2   = 16/2 =8hz

At maximum displacement, the mass must come to a stop before reversing direction

b) its speed is zero
