3.1 3.2 3.3 A small diso, C. is a the roof of a build vertically upwards at a speed of 15 m/s from the edge of height 30 m. AFTER 0.5 a small ball 8 is shot vertically upwards from the foot of the building at a speed of 40 ms in order to hit disc C. Ignore the effects of resistance 15 m/s OC 30 m 40 m-s¹ Explain the term projectile Calculate the: 3.2.1 Time taken by disc C to reach its maximum height (3) 3.2.2 Maximum height above the ground reached by disc C Calculate the time from the moment that disc C was thrown upwards until the time ball B hits the disc. On the same set of axes, sketch graphs of velocity versus time for disk C and ball B from the moment that disc C was thrown upwards until ball 8 hits disc C. Label the graph for ball B as B and the graph for disc C as C. Clearly indicate the following on the graphs: The initial velocities of ball B and disc C The time at which ball B was shot upward 9 The time at which disc C reaches its maximum height The time at which ball B hits disc C 3.4 a 682
