Question

A particle (1) is dropped from a height and another particle (2) 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 (1) will reach at ground first with respect to particle (2)
• D. Particle (2) will reach at ground first with respect to particle (1)

Answer 1

Answer: (A)

Both particles will reach at ground simultaneously

Answer 2

For both cases $t = \sqrt{\frac{2h}{g}} =$constant.

Because vertical downward component of velocity will be zero for both the particles.
