The Correct Option is C
Solution and Explanation
The correct option is(C): 10m
v^2=u^2-2gs=(10)^2-2gh/2=u^2-gh....(1)
0=u^2-2gh=u^2=2gh
putting values of u^2 in(1)
100=2gH-gH=gH
H=100/g=100/10= 10 m.

Concepts Used:
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.
