Question

A ball is thrown vertically upward. It has a speed of 10m/s when it has reached one half of its maximum height. How high does the ball rise?(Taking g=10 m/s2)

• A. 6m
• B. 10m
• C. 14m
• D. 18m

Answer 1

Answer: (B)

10m

Answer 2

From third equation of motion,v2 =u2−2g h

0=u2 −2g ($\frac{h}{2}$)

h=$\frac{u_2}{g}$ = $\frac{10^2}{10}$ ​

=10m

Therefore, the correct option is (B): 10m
