Answer 1

Explanation:

The final velocity v of an object in feet per second (ft/sec) after it slides down a friction less inclined plane of height h feet is v=\sqrt{64 h+v_{0}^{2}}v=

64h+v

0

2

where v_{0}v

0

is the initial velocity (in ft/sec) of the object. (a) What is the final velocity v of an object that slides down a frictionless inclined plane of height 4 feet? Assume that the initial velocity is 0. (b) What is the final velocity v of an object that slides down a frictionless inclined plane of height 16 feet? Assume that the initial velocity is 0. (c) What is the final velocity v of an object that slides down a frictionless inclined plane of height 2 feet with an initial velocity of 4 ft/sec?
