A tennis ball is thrown vertically upward wih an initial velocity of 8.0m/s.
A) What will its speed be wheen it returns to its tarting point?
B) How long will it take for it to reach its starting poing?
(A)Speed = 8m/s
But this is the time required by the tennis ball to reach the highest point.
Time taken by the ball to return to the starting point=2t
A volleyball is thrown vertically upward with an initial velocity of 7.5 m/s.
A.What will its speed be when it return to ita starting point?
B.How long will it take for it to reach its maximum height?
