Question

What is the velocity of a 74.8kg jogger with a kinetic energy of 1085.0 j?

Answer 1

Answer:

5.386m/s

Explanation:

kinetic energy is K = 1/2 *m*v^2

Velocity:

v = (2K / m) ^(1/2)

v = (2 * 1085 (kg*m^2 /s^2) /74.8kg) ^ (1/2)

v = 5,386m/s

(Remember:

N = kg * m^2 / s^2

()^1/2 is equal to square root)
