5. (10 marks) Two blocks A and B are connected by a rigid
bar of negligible weight. Each block has a weight of 10 N.
If the coefficient of static friction between each block and
the surface is S = 0.5, determine the maximum value of
the force P that is possible if the system is not to slip. 6. (12 marks) A ball is thrown from the
top of a 20 m high tower with an initial
velocity of 10 m/s in the direction
(a) Determine the x and y coordinates
of the point at which the ball strikes the
(b) Determine the velocity of the ball at
the point at which it strikes the slope. Total marks for this paper: 60 Time: 3 hours
