Question

A projectile is fired at time t = 0.0 s, from point 0 at the edge of a cliff, with initial velocity components of v ox  {{v}}_{{ox}} = 40 m/s { m m/s} and v oy  {{v}}_{{oy}} = 700 m/s { m m/s}. The projectile rises, then falls into the sea at point P. The time of flight of the projectile is 175 s

In the figure, the horizontal distance D is closest to:

Explanation / Answer

x = vox t = 40*175=7000 m
