Question

Find the velocity of the student using KE= 1/2 mv^2. A 50-kilogram student is running and has 225 joules of kinetic energy. The student’s speed is meters/second

Answer 1

A 50-kilogram student is running and has 225 joules of kinetic energy. The student’s speed is

3

meters/second.

Step-by-step explanation:

Answer 2

225 = 1/2 (50) (v2)
225 = 25 (v2)
225/25 = v2
9 = v2
√9 = v
v = 3 m/s
