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?

• physics -

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.

time=distance/avgvelocity

dint get it can u give me all the steps with the answer to understand it plz
