Question

a projectile has a range of 50 M and reaches at a maximum height of 10 M calculate the angle at which the projectile is fired

Answer 1

For the projectile motion:

H/ R = tan θ / 4
H = 10m.
R = 50m.

Tanθ = 4 × 10/50 = 0.8

θ = Arctan 0.8

Answer 2

For the projectile motion:

H/ R = tan θ / 4
H = 10m.
R = 50m.

Tanθ = 4 × 10/50 = 0.8

θ = Arctan 0.8
