Question

(5)A motorcycle is moving with a velocity of 90km/h and it takes 5 seconds to stop
after the brakes are applied. Calculate the force exerted by the brakes on the
motorcycle if its mass along with the rider is 100kg.​

Answer 1

Answer:

500 N

Explanation:

v = 90 km/h = 90*(5/18) = 25 m/s

F = ma

= 100(25/5)

= 100*5

= 500 N
