Apistol 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.

Explanation:

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

and the initial speed is given as

now we have

now the maximum height of the flare is given as

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

50 inches should be the resultant vector
