Question

Velocity of a body is changed from 2m/s to 8m/s find (a) change in velocity (b) fractional change in velocity (c) percentage of change in velocity

Answer 1

Answer:

a) change in velocity=final velocity-initial velocity

=8-2m/s=6m/s

B) fractional change in velocity=change in velocity/initial velocity

=6/2=3

c) percentage of change in velocity=fractional velocity change x 100

=300
