g is not required if the bike is on a horizontal road.
velocity = 1.3*10^3 m / (14 min * 60 s/min)
= (65/42) m/s
Kinetic energy
= (1/2)mv^2
= (1/2)(57.1)(65/42)^2 J
Shawn and his bike have a total mass of
57.1 kg. Shawn rides his bike 1.3 km in 14 min
at a constant velocity.
The acceleration of gravity is 9.8 m/s
