Shawn and his bike have a total mass of
55.2 kg. shawn rides his bike 1.8 km in
10.5 min at a constant velocity.
the acceleration of gravity is 9.8 m/s
2
.
what is shawn’s kinetic energy

Kinetic energy= 78.86 J

Step-by-step explanation:

Kinetic energy= .5*m*v²

m= 55.2 kg

distance= 1.8 km= 1800m

time= 10.5 min= 630 s

velocity= 1800m/630s= 2.85714

Kinetic energy= .5*55.2*2.85714

Kinetic energy= 78.86 J

Hope this helps
