True/False: A slug is the unit of measure in the English System that is used to determine an object's inertial property 10. Explain how an object falling through air reaches a terminal (constant) speed. 11. True / False: Energy is defined as the ability to move an object through a distance with the application of an applied force. 12. A 5,00 kg backpack falls from a shelf 1,00 m above the floor. What is its speed just before it hits the floor? 13. True/False: The SI unit of momentum is Kg m/s?. True / False: A straight-line distance covered during a certain amount of time describes an object's acceleration 14. 15. What is power? 16. Acceleration occurs when an object undergoesExplanation / Answer
7) We know that power P has units watt and horse power
1 horse power = 550ft-lb per s
so the answer for 7) is d
8) Net Force is Fnet = m*a
16 = m*5
m = 16/5 = 3.2 kg
weight is w = m*g = 3.2*9.81 = 31.4 N
