Question

What is the total kinetic energy of a 0.15 kg hockey puck sliding at 0.5 m/s and rotating about its center at 8.4 rad/s

Answer 1

`K=0.023J`

Step-by-step explanation:

From the question we are told that:

Mass
`m=0.15`

Velocity
`v=0.5m/s`

Angular Velocity
`\omega=8.4rad/s`

Generally the equation for Kinetic Energy is mathematically given by

`K=(1)/(2)M(v^2+(1)/(2)R^2\omega^2)`

`K=(1)/(2)0.15(0.5^2+(1)/(2)(0.038)^2.(8.4rad/s^2))`

`K=0.023J`
