A block is projected up a frictionless inclined plane with initial speed v0 = 8.42 m/s. The angle of incline is è = 58.4°. (a) How far up the plane does it go? (b) How long does it take to get there? (c) What is its speed when it gets back to the bottom?
set the intial KE equal to mgh. Solve for H.
then the distance up the plane is given by H=distance*sin58.4
Its speed at the bottom, the same as the initial speed, reversed in direction.
Howlong up the ramp? Average velocity=4.24m/s, distance you solved.
dint get it can u give me all the steps with the answer to understand it plz
