A 5.40-kg block is set into motion up an inclined plane with an initial speed of vi = 7.40 m/s (see figure below). The block comes to rest after traveling d = 3.00 rn along the plane, which is inclined at an angle of 9 = 30.0" to the horizontal. 4/\" 730 G) (a) For this motion, determine the change in the block's kinetic energy. J H (b) For this motion, determine the change in potential energy of the blockEarth system. J H (c) Determine the friction force exerted on the block (assumed to be constant). N H (d) What is the coefcient of kinetic friction? H Need Help? __
