Question

what velocity must a 1340kg car have in order to have the same momentum as a 2680kg truck traveling at a velocity of 15 m/s to the west

Answer 1

IR = Q

Q = m . v

Qtruck = 2680 . 15

Qt = 40.200 kg . m/s

Then,

Qcar = Qt

m . V = 40 . 200

1340 . V = 40.200

V = 40 . 200 / 1340

V = 30 m / s
