Question

A device launches horizontally two identical balls (A and B) simultaneously (at the same
instant of time) from the same height h = 5m. If the initial speed of ball A is vA =
2m/s and the initial speed of ball B is vig = 4m/s, then:
(g 10m/s)
Launch device
A Both balls (A and B) would hit the ground at the same time t = 1s.
B Both balls (A and B) would hit the ground at the same time t= 2s.
C Both balls (A and B) wvould hit the ground at the same time t= 15s.
D. Ball A would hit the ground after time t= Is and ball B would hit the ground after time t = 2s.
E Ball A would hit the ground after time t 2s and ball B would hit the ground after time t 1s.
A ball is kicked from the ground at point O with an intial velocity 1 = 20 m/s that
makes an agle 0= 30° with the horizontal This ball reaches its maximum height at
pouLA and then returns to the ground at point B as shown in the figure (g 10m/s")
The tine taken by the ball to reach the maximurm height at point A (toA) is equal to:
