Question

A car of mass 1050kg is moving with velocity 10m/s. Calculate the momentum

Answer 1

Answer:

Explanation:

Correct option is

B

15m/s

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=  

m

F−f

​

=  

1000

1000−500

​

=0.5 m/s  

2

 

Using      v=u+at

∴   v=10+0.5×10=15 m/s
