I get most of the things in my textbook, such as mgh,Fs and 1/2mv squared. But I don't understand things about stopping force and stuff.
heres a practice question i got(i have a test 2morrow):
A boy of mass 50 kg rides on a bicycle of mass 15 kg at a speed of 15 m/s. He suddenly applies the braked and brings the bicycle to a stop in 25m. What force did the brakes apply to the wheels as he was stopping?
I really don't understand how to do this... please help!
