A car having aa mass 700 kg is moving at a speed of 90 km/h . on applying brakes , its speed is reduced to 36km/h in 10 s . Calculate the force applied by the brakes .

m = 700 kg 
u = 90 km/h = 90*5/18 m/s = 25 m/s 
v = 36 km/h = 36 * 5/18 = 10 m/s 
t = 10 s 
a = ? 
F ? 


The force applied by the brakes is 1050 N in the opposite direction
