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

Question 148

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 v0x=30 m/sv _ { 0 x } = 30 \mathrm {~m} / \mathrm { s } and v0y=300 m/sv_ { 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 s,75.0 \mathrm {~s} , and air resistance is negligible. At this location, g = 9.80 m/s2. What is the horizontal distance D?
