24. Two objects are connected by a light string that passes
over a frictionless pulley as shown in Figure p5.24.Draw
free-body diagrams of both objects.
37. Two blocks connected by a rope of negligible mass are being
dragged by a horizontal force(FigP5.37).Suppose F=68.0N,m1=
12.0kg,m2=18.0kg,and the coefficient of kinetic friction between
each block and the surface is 0.1.
14. A roller-coaster car (FigP6.14) has a mass of 500kg when fully loaded
with passengers.
25. A small piece of Styrofoam packing material is dropped
from a height of 2.00m above the ground.
45. An amusement park ride consists of a rotating circular
platform 8.00m in diameter from which 10.0kg seats suspended
at the end of 2.50m massless chains(Fig P6.45).
