Question

Please help me to answer this problem . its is my
Project in Physics

- A 1000kg motorcycle carrying a 70kg rider comes to a stop 40m from a speed of ah 50km/h when it brakes are aplied in the force excerted by the brake and the force experiment by the rider .

Please answer i need it now :(

Answer 1

Let
M = mass of motorcycle
m = the mass of rider
a = average (retarding) acceleration
s = distance traveled under retardation
u = initial speed

Use -
2as = u^2 (don't worry about sign of a)

Force exerted by brake = (M+m)a
Force experienced by the rider = Pseudo force from his frame of reference
