A long, very smooth board is inclined at an angle of 10° with the horizon- tal. A weight starts from rest 10 ft from the bottom of the board and slides downward under the action of gravity alone. Find how long it will take the weight to reach the bottom of the board and determine the terminal speed.

A particle moves in a straight line with a constant starting velocity of 45 m/sec within 12 sec. then slows down to -25m/sec within 16 sec and with that constant velocity within 14 sec. when it starts to speed up at 5 m/sec within 4sec. and constantly until it reach a total time travel of 50 sec. Knowing that x = -520 m at t=0, (a) construct the a-t and x-t curves for 0<t<50sec,determine themaximum acceleration of the particle within 5 sec. and determine (b) the maximum position of the particle (c) the time/s when x=0 (8) the maximum acceleration of the particle within 50 sec.
