Question

9) How much kinetic energy does a person have riding a bike is going 12 m/s? Let's assume that the

bike and person have a mass of 70kg.
A)
B)
C)

Answer 1

Kinetic Energy =
`(1)/(2) m*v^2`

• m: mass -->70 kg
• v: velocity --> 12 m/s

Kinetic energy =
`(1)/(2)*70*(12^(2) ) = 5040` Joules

Hope that helps!
