Download The roller at A is moving upward with a velocity

1- The roller at A is moving upward with a velocity of vA = 3 ft/s and has an
acceleration of aA = 4 ft/s2 when sA = 4 ft. Determine the velocity and acceleration
of block B at this instant. 12-196
2- The stones are thrown off the conveyor with a horizontal velocity of 10 ft/s as
shown. Determine the distance d down the slope to where the stones hit the ground
at B.
3- The sled and rider have a total mass of 80 kg and start from rest at A(10 m, 0). If the sled descends the
smooth slope, which may be approximated by a parabola, determine the normal force that the ground exerts on
the sled at the instant it arrives at point C. Neglect the size of the sled and rider. Hint: Use the result of Prob.
