physics question help help not sure?

Do U have a pencil handy :>)

1) First sketch the ramp and box.

2) Calculate the weight (mg) of box and show it as a vector on UR sketch.

3) Sketch two components of weight vector, parallel and perpendicular to ramp

4) Mathematically compute using sin & cos, the sizes of these components

5) The perpendicular component = Normal force, from it compute: µk(N) = (0.24N) = fk

6) Sketch the kinetic friction force (fk) vector {size computed in 5)} on UR diagram

7) Compute {see UR diagram} the NET FORCE (Fnet) that acts down ramp.

{Fnet = weight component parallel to ramp - fk}

8) Compute the NET ACCELERATION that acts down the ramp = a = Fnet/m {m = 55}

9) Use kinematic relationship: (Vf)² = (Vi)² - 2ad {Vi = 0.45, "a" from 8), d = 2.1}

solve 9) for Vf = ANS
