A projectile is launched at an angle of 30 degrees above the horizontal with an initial velocity of 40 m/s. What is the maximum height reached by the projectile?

Given:

Initial velocity (V) = 40 m/s

Launch angle (θ) = 30 degrees

Acceleration due to gravity (g) = 9.8 m/s2

Using the kinematic equation: Vf2 = Vi2 + 2 x a x Δy

Since the maximum height is reached when the vertical velocity becomes zero, we can set Vf = 0.

0 = (40 x sin(30))2 + 2 x (-9.8) x Δy

0 = 400 x (1/2)2 - 19.6 x Δy

0 = 100 - 19.6 x Δy

Solving for Δy:

Δy = 100 / 19.6

Δy ≈ 5.102 metres

Therefore, the maximum height reached by the projectile is approximately 5.102 metres.
