Question

bullet train in the velocity of 180 kilometre per hour and it takes 5 seconds to stop after the brakes are applied find the force exerted on the brakes on the wheel of pain if its mass with the Baigan is 2000 kg...???​

Answer 1

Answer:

Heya...

Initial velocity = 180km/hr = 50m/s

Final Velocity = 0

Time= 5 s , mass = 2000 kg

From first equation on motion,

v = u + at

u = -at

a = -(u/t) = -10m/s²

From newton's second law,

Force = mass × acceleration

F = 2000 × (-10)

F= (-20000)
