(i) Determine which of the vectors b or a is perpendicular to a.
Two smooth spheres, S and T, each of mass m lie on the plane ll. Sphere S is projected along the plane towards sphere T with velocity 5x(i + 2j) so that it collides obliquely with T. At the instant of collision, the line of impact is parallel to the vector a. Given that the coefficient of restitution between the two spheres is 1/2,
Show that
(ii) the component of the initial velocity of S parallel to a is 11x.
(iii) the component of the final velocity os S parallel to a is (11/4)x.
(iv) the magnitude of the impulse exerted by sphere T on sphere S is (33/4)mx.

A teacher places 10 differently coloured beanbags on the classroom floor. Each
beanbag is spaced a step apart. The teacher gives Mpho (5 years old) the following
instructions and observes her: Take 4 steps forward on the mats. Now take 3 more
steps from where you are. What number mat did you land on? Now, Mpho, take 2
steps backwards. What is the number of the mat on which you landed?
