Question

Define the projectile? Find the expresion for maximum height,equation of trajectory and horizontal range for a projectile fire at an angle thita horizontal?

Answer 1

Projectile is a body which is given an initial velocity and moves in space under the influence of gravity alone.

Max height (H)= u^2sin^2 teta/2g

Horizontal range (R)= u^2 sin2teta/g

If a projectile is launched with an initial velocity u from the horizontal position at an angle ● then it's vertical path (y) can be calculated from its horizontal position
y = xtan● - gx^2/2u^2 cos^2●
