Question

So it takes $\frac{u}{g}$secs to go up, how long will it take to come down?(as mentioned there is no air)

• A. longer than $\frac{v}{g}$
• B. shorter than $\frac{v}{g}$ because in the previous case gravity is acting against velocity and here it is acting along the velocity
• C. equal to $\frac{v}{g}$
• D. I don't know

Answer 1

The correct option is C

equal to $\frac{v}{g}$
