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

question 30

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
