Q 1) a ball is thrown at 30m/sec from 100 m tall buliding. take the ground as origin when it strikes it. draw x-t , a-t , and v-t, graph.
Q2) a ball is thrown at 20 m/sec from origin from 50 m tall building . draw x-t , v-t , a-t graph.

Expert Answer
It is assumed that ball is thrown vertically downwards with speed 30 m/s.
vertical position as a function of time is plotted in x-t graph.
vertical position = 100 - [ ut +(1/2)gt2 ] , where u is initial velocity 30 m/s , t is time and g is acceleration due to gravity
velocity of the ball as a function of time is plotted in v-t graph, v = u+gt , where v is velocity at time t
acceleraion g = 9.8 i s uniform throughout the motion as plotted in a-t graph
