Question

A pistol that fires a signal flare gives it an initial velocity (muzzle velocity) of 173 m/s at an angle of 62.9 ∘ above the horizontal. You can ignore air resistance. Find the flare's maximum height if it is fired on the level salt flats of Utah.

Answer 1

Answer:

$y_{max} = 1208.8 m$

Explanation:

As we know that flare is shot at an angle of 62.9 degree

and the initial speed is given as

$v_i = 173 m/s$

now we have

$v_y = v sin\theta$

$v_y = 173 sin62.9$

$v_y = 154 m/s$

now the maximum height of the flare is given as

$y_{max} = \frac{v^2}{2g}$

$y_{max} = \frac{154^2}{2(9.81)}$

$y_{max} = 1208.8 m$
