1.	A motorcar is moving with a velocity of 108 km/h and it takes 4 s tostop after the brakes are applied.Calculate the force exerted by thebrakes on the motorcar if its mass alongwith the passengers is 1000 kg.
Answer» U= 108 km/hr = 30 m/sv= 0t= 4 secsv = u + at0 = 30 + 4aa = -30/4Now F = ma = 1000 X (-30/4) = -7500 N
