A motor scooter travels east at a speed of 13 m/s. The driver then reverses direction and heads west at 17 m/s. What was the change in velocity of the scooter?
Dear sachin,
the velocity of scooter in vector form is
V1 = 13i
Vfinal = -17 m/s
change in velocity = Vf - V intial
= -17-13 = -30 m/s
Hence change in velocity = -30 m/s
