A 1200-kg car moving at 20 km/h is accelerated
1 answer:
Answer:
Force on the car will be 4800 N and time required to cover this distance 13.75 sec
Explanation:
We have given mass of the car = 1200 kg
Initial velocity u = 20 km/h
Final velocity v = 75 km/h
Acceleration
From the first equation of motion we know that
v = u+at, here v is final velocity, u is initial velocity, a is acceleration and t is time
So
t = 13.75 sec
From second law of motion we know that
So force
