A 1,500 kg car coasts down a hill starting from rest and decreases its height by 22 m over a distance of 100 m of travel. How fast will it be going at the end of the hill, if friction has no effect in slowing its motion?

21 m/s *me answer*

15 m/s

44 m/s

wheres your work or at least a thought process

anonymous · Answer

ok so :

so (1/2)mv² = mgΔh 

v² = 2gΔh 

v = √[2 * 9.8 * 22] 

v = 21 m/s
