AIPMT PRELIMS 2005 Physics Projectile Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
A ball is thrown vertically upward. It has a speed of 10 m/s when it has reached one half of its maximum height. How high does the ball rise? (Taking g = 10 m/s²)
A
6 m
B
10 m
C
14 m
D
18 m
Correct Answer
Option B
Detailed Explanation
Using energy conservation, at half the maximum height, the kinetic energy is half of the initial kinetic energy. Solving for maximum height using v² = u² - 2gh gives h = 10 m.
