Question

A vehicle of mass 1500kg is moving with a velocity 15m/s. a force 1000N is applied to the direction of motion. what will be the velocity after 15second.
​

Answer 1

Answer:

15 m/s

Explanation:

Given :   m=1000 kg               u=10 m/s              t=10 s

Applied force  F=1000 N      (forwards)

Retarding force  f=500 N      (backwards)

Acceleration of the car in forward direction

a=mF−f​=10001000−500​=0.5 m/s2

Using,v=u+at

∴   v=10+0.5×10=15 m/s
