A 10.0-kg block is released from rest on a frictionless track inclined at an angle of 55°. (a) What is the net force on the block after it is released? (b) What is the acceleration of the block? (c) If the block is released from rest, how long will it take for the block to attain a speed of 10.0 m/s? (d) Draw a motion diagram for the block, (e) Draw a graph of vx(t) for values of velocity between 0 and 10 m/s. Let the positive .x-axis point down the track.
