Answer to Question #348516 in Physics for Yannis

Question #348516

A person does 360J of work in 3.2s to accelerate a bike at 13m/s^2. This changed the velocity by 31m/s. How heavy is the bike. The bike moved 26m

Expert's answer

"W=Fd"

"F=\\frac{W}{d}=\\frac{360}{26}=13.8\\:\\rm N"

"F=ma"

"m=\\frac{F}{a}=\\frac{13.8}{13}=1.1\\:\\rm kg"
