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?

Answer 1

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
