A mass m = 14 kg is pulled along a horizontal floor with NO friction for a distance d =5.5 m. Then the mass is pulled up an incline that makes an angle = 33 with the horizontal and has a coefficient of kinetic friction _k = 0.47. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of = 33 (thus on the incline it is parallel to the surface) and has a tension T =58 N.

1)What is the work done by tension before the block goes up the incline? (On the horizontal surface.)

_ J

2)What is the speed of the block right before it begins to travel up the incline?

_ m/s

3)What is the work done by friction after the block has traveled a distance x = 2.2 m up the incline? (Where x is measured along the incline.)

_J

4)What is the work done by gravity after the block has traveled a distance x = 2.2 m up the incline? (Where x is measured along the incline.)

_ J

5)How far up the incline does the block travel before coming to rest? (Measured along the incline.)

_m

6)On the incline the net work done on the block is:

zero

positive

negative
