Question

A particle moves according to the law of motion s(t) = t^3 - 8t^2 + 3t, t ? 0, where t is measured in seconds and s in feet. a.) Find the velocity at time t. Answer: b.) What is the velocity after 3 seconds? Answer: c.) When is the particle at rest? Enter your answer as a comma separated list. Enter None if the particle is never at rest. At t1 = and t2 = with t1 < t2. d.) When is the particle moving in the positive direction? When 0 ? t < and t >

Step 1

a) The velocity function is given by v(t) = ds/dt = d(8t^2 + 3t)/dt. Using the power rule, we get: v(t) = 16t + 3 b) Show more…
