Question 200: Motion in 2D & Vectors

Question

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

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
o
= 0) direction. Hence they will
reach the ground simultaneously.

Answer

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

Answer

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

Answer

both particles will reach at ground simultaneously

Answer

both particles will reach at ground with same speed.
