A motorcycle and rider have a total mass equal to 300 kg. The rider applies the brakes, causing the motorcycle to accelerate at a rate of -5 m/s2. What is the magnitude of the net force on the motorcycle? ______N
There are special bits for this. And you'll need a darned heavy duty drill. Your local hardware store can show you the right stuff.

Let the motorcycle take t sec to fall 50 m By s ut + 1/2gt^2 50 0 + 1/2 x 9.8 x t^2 t √10.20 t 3.19 sec By R [Ux] x t 90 u x 3.19 u 28.17 m/s
Force mass * acceleration (in this case deceleration) 300 * -5 - 1500 N (Newtons or kg m/s^2)
