Question

A flare is fired at an angle of 35 degrees to hit the ground at an initial speed of 250 m/s. How long dies it take for the flare to reach its maximum altitude?
The time it takes for the flare to reach its maximum altitude can be calculated using the equation:

t = v₀sin(θ) / g

where v₀ is the initial velocity, θ is the angle of launch, and g is the acceleration due to gravity (9.8 m/s²).

Plugging in the given values, we get:

t = 250sin(35) / 9.8 = 8.2 s
