Exercise 3/46

• With the blocks initially at rest, the force P is
  increased slowly from zero to 60 lb. Plot the
  accelerations of both masses as functions of P.

Sample 3/8

• A 1500-kg car slows down at a uniform rate from a
  speed of 100 km/h at A to 50 km/h as it pass C.
  Point B is the inflection point where the
  curvature changes direction.
• Determine the horizontal force exerted by the
  road on the tires at A, B, C.

5
Exercise 3/50

• A 2-kg block passes over the top B of the
  circular potion of the path with a speed v3.5
  m/s. Calculate the normal force exerted by the
  path on the block.
• What is the maximum speed v the block can have at
  A without losing contact with the path.
