Question

A ball is thrown upwards with the velocity of 50 m s^-1 making an angle of 60° with the vertical. What is the ratio of time of ascent to time of descent?
(Take g = 10 m s^-2)

• A. 1 : 1
• B. 1 : 2
• C. 2 : 1
• D. $\frac{1}{2}:\frac{1}{3}$

Answer 1

The correct option is A

1 : 1

1. For all types of the projectile time of ascent is always equal to the time of descent.
2. If the time of ascent is T the time of descent will also be T.
3. So the ratio of the time of ascent to the time of descent will always be 1: 1

Hence the correct option is (A) 1 : 1
