A particle moves according to a law of motion s = f(t), t ≥ 0, where t is measured in seconds and s in feet. f(t) = t3 − 9t2 + 24t.
- (a) Find the velocity at time t.
- (b) What is the velocity after 1 second?
- (c) When is the particle at rest?
- (d) When is the particle moving in the positive direction?
- (e) Find the total distance traveled during the first 6 seconds.
- (f) Draw a diagram like Figure 2 to illustrate the motion of the particle.
- (g) Find the acceleration at time t and after 1 second.
