F*t=mv-mu

anonymous · Answer

thank you, can you possibly tell me what each of those values represent?

shamim · Answer

F=force
m=103kg
u=13.9m/s
v=1.4m/s

shamim · Answer

do u need any more explanation

anonymous · Answer

it was multiple choice, 
1.2 × 10^4 newtons

1.4 × 10^4 newtons

1.6 × 10^3 newtons

1.6 × 10^2 newtons

Based on my calculations, I chose 1.4 x 10^4, is that correct?
