Question

Shawn and his bike have a total mass of
58.5 kg. Shawn rides his bike 0.54 km in 17.2 min at a constant velocity. The acceleration of gravity is 9.8 m/s^2. What is Shawn’s kinetic energy?
Answer in units of J.

Answer 1

Use equations: KE=.5*m*v^2 and v=d/t

KE=.5*m*(d/t)

KE=.5*58.5*(540/(17.2*60))

KE=15.3 J
