a) What initial speed must the rocket have? (Assume that the only force acting on the rocket after it is blasted from the top of the mountain is gravity.)

b) How long would rocket spend in the air?

I need help with this problem.

I dont know how to start this question, i know that its projectile and i can use the maxHeight and Range equation but the question only gives the height from the top of the mountain to the ground and the distance travelled.

Thank you.
