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?

$\huge {\pink {\underline {\underline {\mathbb { Answer :- }}}}}$

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

Answer 2

Answer:

v = u + at

a = (v - u) / t

a = 108/4 = 27 m/s^2

Force ( f ) = ma = 1000 × 27 = 27000 N
