Question

A vehicle having mass of 1000 kg is running with speed of 10m/s. After applying a force of 1000N for 10 sec , what will be the speed of vehicle?


Please give step by step answer!​

Answer 1

Explanation:

vehicle having mass equal to 1000 kg is running with a speed of 5m/s. After applying the force of 1000N for 10 second what will be the speed of vehicle? Therefore, Final velocity (v) =? Thus, the velocity of the vehicle will be 15m/s.

Answer 2

Explanation:

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

Acceleration of the vehicle        a=mF=10001000=1  m/s2

Using     v=u+at

∴   v=10+1×10                    ⟹v=20  m/s
