Question

A boy bats a ball with a certain initial velocity at an angle of 34 deg above horizontal. in 1.9s ball reaches its highest point. whats initial velocity of the ball

Answer 1

19. A student drops a ball from a window. 3.5 m above the sidewalk. The ball ... Hint: Its acceleration is the same whether it is moving up or down. d. 0. 2.5 m d. 1 ..... At point D, 30 m east of the origin ...... Initial Velocity. (m/s). Braking Distance. (m). 11. 10. 15. 20. 20. 34. 25. 50. 29 ...... make an angle of 42° with the horizontal.

Answer 2

given that \[\theta = 34\]
and at the highest point the the velocity in y direction is zero
\[Vy=Vosin \theta -Gt\]
which is zero
therefore
Vo=Gt/sin34
