A ball is thrown vertically. It has a speed of 10 ~m / sec when it has reached one half of its maximum height. How high does the ball rise? Take g =10 ~m / s ^2 .

Options

  1. A10 ~m
  2. B5 ~m
  3. C15 ~m
  4. D20 ~m

Correct answer

A. 10 ~m

Step-by-step solution

Using equation of motion V^2=u^2-2 g h After reading max height velocity because zero. aligned 0 & =(10)^2-2 10 1 2 h & = 200 20 =10 ~m aligned
