As Shown in the Figure, a Projectile Is Fired at Time

question 19

Multiple Choice

As shown in the figure, a projectile is fired at time t = 0.00 s, from point 0 at the upper edge of a cliff, with initial velocity components of $v 0 x = 30 \mathrm {~m} / \mathrm { s }$ and $v 0 y = 300 \mathrm {~m} / \mathrm { s }$ The projectile rises and then falls into the sea at point P. The time of flight of the projectile is $75.0 \mathrm {~s} ,$ and air resistance is negligible. At this location, g = 9.80 m/s². What is the horizontal distance D?

• A) 2250 m
• B) 2520 m
• C) 2790 m
• D) 3060 m
• E) 3330 m
