Given :
A 1200 kg truck traveling at 20 m/s towards the east.
To Find :
The magnitude and direction of the momentum.
Solution :
We know, momentum is given by :
Momentum, P = mv
P = 1200 × 20 kg m/s
P = 24000 kg m/s
Now, we know, direction of momentum is same as the direction of velocity.
Therefore, momentum of truck is 24000 kg m/s and direction is towards the east.
