question 24

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 effects are 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
