(a) Find the impulse for the interval from t = 0 to t = 3.0 s.
N\cdot s
(b) Find the impulse for the interval from t = 0 to t = 5.0 s.
N\cdot s
(c) If the forces act on a 6.7-kg particle that is initially at rest, find the particle's speed at t = 3.0 s.
m/s
(d) If the forces act on a 6.7-kg particle that is initially at rest, find the particle's speed at t = 5.0 s.
