Question

A particle A is dropped from a height and another particle B is projected in horizontal direction with speed of 5 m/ sec from the same height then correct statement is: (A) particle A will reach at ground first with respect to particle B (B) particle B will reach at ground first with respect to particle A (C) both particles will reach at ground simultaneously (D) both particles will reach at ground with same speed

Tardigrade Admin · Accepted Answer

Time required to reach the ground is dependent on the vertical motion of the particle. Vertical motion of both the particles A and B are exactly same. Although particle B has an initial velocity, but that is in horizontal direction and it has no component in vertical (component of a vector at a direction of 90°=0 ) direction. Hence they will reach the ground simultaneously.

Q. A particle A is dropped from a height and another particle B is projected in horizontal direction with speed of 5m/sec from the same height then correct statement is:

particle A will reach at ground first with respect to particle B

particle B will reach at ground first with respect to particle A

both particles will reach at ground simultaneously

both particles will reach at ground with same speed

Q. A particle $A$ is dropped from a height and another particle $B$ is projected in horizontal direction with speed of $5 m / sec$ from the same height then correct statement is:
