TRUE OR FALSE Plz help me 6. The amount of work done on an object depends on the final speed of the object.

7. 1 Horsepower (hp) is equal to 746 Watts.

8. The SI unit for Work is the Joule.

9. The lower the percentage, the better the efficiency.

10. The Work-Energy theorem states that the change in kinetic energy also equals the amount of work done on an object or system. ​

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
