Question 169: Motion in 2D & Vectors

Question

A cricket ball is thrown by a player at a speed of 20 m/s in a direction 30$$^\circ$$ above the horizontal. The maximum height attained by the ball during its motion is
(g = 10 m/s
2
)

Accepted Answer

Maximum height reached by the ball
$$H = {{{v^2}{{\sin }^2}	heta } \over {2g}}$$
$$ = {{{{(20)}^2}{{\sin }^2}30^\circ } \over {2g}}$$
$$H = 5\,m$$

Answer

25 m

Answer

5 m

Answer

10 m

Answer

20 m
