Question:
A ball $P$ is dropped vertically and another ball $Q$ is thrown horizontally with the same velocities from same height and at the same time. If an resistance is neglected, then
A ball $P$ is dropped vertically and another ball $Q$ is thrown horizontally with the same velocities from same height and at the same time. If an resistance is neglected, then

- ball $P$ reaches the ground first
- ball $Q$ reaches the ground first
- both reach the ground at same time
- the respective masses of the two balls will decide the time.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Both P and Q have same initial velocity and same acceleration due to gravity so both will reach the ground at the same time.

Motion in a straight line
The motion in a straight line is an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. It is nothing but linear motion.
Types of Linear Motion:
Linear motion is also known as the Rectilinear Motion which are of two types:
- Uniform linear motion with constant velocity or zero acceleration: If a body travels in a straight line by covering an equal amount of distance in an equal interval of time then it is said to have uniform motion.
- Non-Uniform linear motion with variable velocity or non-zero acceleration: Not like the uniform acceleration, the body is said to have a non-uniform motion when the velocity of a body changes by unequal amounts in equal intervals of time. The rate of change of its velocity changes at different points of time during its movement.
