Question

force of 4000 Newton is repuired to pull the car of mass 500kg from rest to 2meter per second in 5seconds the work done by car engine is? ​

Answer 1

Explanation:

Answer

The acceleration of the car is given as,

v

2

=u

=0+2×a×25

a=8m/s

The force is given as,

F=ma

=500×8

=4000N

Thus, the average force needed to accelerate the car is 4000N.
