29 4 points A mass on a spring vibrates horizontally on a smooth level surface (see the figure). Its equation of motion is x(t)E 10 sin t, where t is in seconds and x is in centimeters. equilibrium position (a) Find the velocity and acceleration at time t a(t) (b) Find the position, velocity, and acceleration of the mass at time t 5T/6 In what direction is it moving at that time? left right Is it speeding up or slowing down?

My Note I SEssC. ET2 2.4 VE.00Explanation / Answer
a)
v = 10 cos t
a = -10 sin t
b) x = 10 * sin 150 = 5
v = 10 * cos 150 = -8.66
a = -10 sin 150 = -5
c) left
d) speeding up
