easy

A particle $(A)$ is dropped from a height and another particle $(B)$ is thrown in horizontal direction with speed of $5\; m/sec$ from the same height. The correct statement is

A

Both particles will reach at ground simultaneously

B

Both particles will reach at ground with same speed

C

Particle $(A)$ will reach at ground first with respect to particle $(B)$

D

Particle $ (B) $ will reach at ground first with respect to particle $(A)$

(AIPMT-2002)

Solution

(a)For both cases $t = \sqrt {\frac{{2h}}{g}} = $constant.
Because vertical downward component of velocity will be zero for both the particles.
