What is the kinetic energy of a 1850 kg car that is traveling at 58.0 km/h? B. How much work was done to give the car this kinetic energy assuming the car starts from rest? C. How much work must be done to stop the car?

Answer 1

change km/hr to m/s

KE=1/2 m v^2

it took that much work to give it that much KE

Same amount
