1). Shawn and his bike have a total mass of 45.0kg. Shawn rides his bike 1.80km in 10.0 min at a constant velocity. What is Shawn's kinetic energy?(adsbygoogle = window.adsbygoogle || []).push({});

m=45.0kg (Shawn+Bike total mass)

t=10.0min-->600sec

d=1.80km-->1,800m

K=1/2mv^2.

so...K=1/2(45.0kg)(???)^2

I'm assuming v=3m/s

Therefore v=3.0m/s?
