Question

1. 12 points PSE6 5.P.025. My Notes A block is given an initial velocity of 4.00 m/s up a frictionless 20.0° incline (Figure P5.22) How far up the incline does the block slide before coming (momentarily) to rest? Figure P5.22

Answer 1

Given is:-

Initial velocity of the block  

angle of inclination  

Now,

the free body diagram will be as shown below:-

Thus the declearation along the surface will be

by plugging all the values we get

Now

using third equation of motion we get

which gives us

Hence

the block slides for 2.39m before coming to rest
