From Newton's second law of motion:
.where P is momentum and t is time, F is force. Hence,
a) t = 4 s.
P = area under curve from t = 0s to t = 4s.
P = 0.5*(4+2)*30 = 90 N s.
b) t = 9 sec.
P = 0.5*(6+2)*30-0.5*(3+1)*15 = 120-30 = 90 Ns.
c) velocity at t = 4s,
v = P/m = 90/3 = 30 m/s
d) velocity at t = 9s.
v = P/m = 90/3 = 30 m/s.
