Question

A ball is thrown at a speed of 20 m $s^{-1}$ at an angle of $30^{0}$ with the horizontal. The maximum height reached by the ball is ($g=10~ms^{-2}$)}

• A. 2 m
• B. 3 m
• C. 4 m
• D. 5 m

Hint:

Vertical component of velocity is $u \sin \theta$. Height depends only on this vertical component ($v_{y}^{2}/2g$).

Answer 1

The Correct Option is D
