A75-kilogram bicyclist coasts down a hill at a constant speed of 12 meters per second. what is the kinetic
energy of the bicyclist?
(1) 4.5 × 10^2 j (3) 5.4 × 10^3 j
(2) 9.0 × 10^2 j (4) 1.1 × 10^4 j

(3) 5.4 × 10^3 J

Explanation:

The kinetic energy of the bicyclist can be calculated using the following equation:

where

m = 75 kg is the mass of the bicyclist

v = 12 m/s is the speed of the byciclist

By substituting these numbers into the equation, we find:

So, the correct answer is

(3) 5.4 × 10^3 J

answer: the answer is a

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
