Question

A projectile will cover the maximum vertical distance in the minimum time when the angle of its projection with the vertical is:
(a) 0 ⁰
(b) 30⁰
(c) 60 ⁰
(d) 90⁰​

Answer 1

Answer:

I think (d) but iam not sure

Explanation:

Maximum height of projection is

H=(V^2sin^A)÷2g where A is the angle of projection

Therefore H is maximum when sinA=1

therefore A=90

Iam not sure about the answer
