Question

If a projectile is launched with angle $\theta$ to the horizontal inside a lift going up with acceleration a, its range is:

• A. $u^{2}sin\left(2\theta \right)/g$
• B. $u^{2}sin\left(2\theta \right)/(g+a)$
• C. $u^{2}sin\left(2\theta \right)/a$
• D. Man, this makes no sense to me.

Answer 1

The correct option is B $u^{2}sin\left(2\theta \right)/(g+a)$
