Calculate the force required to raise a car a velocity of 40 m/s in 10 sec starting from rest. The mass of the car is 1500 kg.

Text Solution

Verified by Experts

Here, mass (m)=1500 kg,
Initial velocity (u)=0, final velocity (v)=40 m/s, Time take (t)=10 s
`therefore`Force required, F=ma
`=m((v-u)/(t))=1500((40-0)/(10))N=(1500xx(40)/(10))N=6000N`
