A 56.5-kg box is pulled by a rope making an angle of ? = 21.5° with the horizontal. The tension in the rope is 27.5 N. (Assume the surface the box slides across is frictionless.) If the box starts from rest, determine the time required to move the box a horizontal distance of 2.31 m.

Question 4.3b:
The figure shows two blocks connected by a lightweight string across a frictionless pulley. The hanging block has mass m1 = 5.65 kg and the second block has mass m2 = 3.90 kg. The ramp is frictionless and inclined at an angle of ? = 44.0° from the horizontal. When released from rest, block 1 will descend and block 2 will move up the ramp. (Assume the ramp is frictionless.)
Determine the magnitude of each block's acceleration and the tension in the string.
