girl-car system

​

Answer 1

Answer:

Calculate the K.E. of a 2000kg car that is moving (a) at 10.0m/s, ... Example 9: A 750-kg car is traveling at a velocity of 72km/h eastward and on a level road. ... 12) When a car is driven to the top of a hill, there is an increase in its (a) K.E. ... energy losses, the total mechanical energy of a system remains constant.
