Answer:
=>By the work energy relation:-
=>W = ∆KE
=>Ff.s = 1/2(M+m)v^2
=>µk x N x s = 1/2(M+m)v^2
=>µk x (M+m) x g x s = 1/2(M+m)v^2
=>v = √[2µkgs]
=>v = √[2 x 0.82 x 9.8 x 10.6]
=>v = 13.05 m/s
By the law of momentum conservation:-
=>Mu = (M+m)v
=>9230u = (9230+1250) x 13.05
=>u = 14.82 m/s

Answer:
320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.
