A car moving with the speed of 108 km/h comes to rest after 4s on applying brake.If the mass of the car including the passengers is 1000 kg,what will be the force applied when brake is applied?
Given :-
initial velocity = 108 kmph
Final velocity = 0 kmph
Time = 4 sec
Mass = 1000 kg
To find :-
Force = ?
Solution :-
v = u + at
a = (v - u) / t
a = 108/4 = 27 m/s^2
Force ( f ) = ma = 1000 × 27 = 27000 N
