9. A golfer can hit a golf ball a horizontal distance of over 300m on a good drive. What maximum height will a 301.5m drive reach if it is launched at an angle of 25.0" to the ground? (Hint: At the top of its flight, the ball's vertical velocity component will be zero). 70.3m 10. A ship maneuvers to within 2.50 x 103m of an island's 1.80 x 103m high mountain peak and fires a projectile at an enemy ship 6.10 x 102m on the other side of the peak. If the ship shoots the projectile with an initial velocity of 2.50 x 102m/s at an angle of 75.0", how close does it come to hitting the enemy ship? How close does it get to hitting the mountain peak? t It misses the ship by 80m. It clears the peak by 210m. 11. A cacis parked on a cliff overlooking the ocean on an incline that makes an angle of 2.4.0\" below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The gcar rolls from rest down the incline with a constant acceleration of 4.0Clm/s2 and travels 50.0m to the edge of the cliff. The cliff is 30.0m above the ocean. How far does the car travel after leaving the cliff? How long does it take for the car to hit the water? 32.5m, 1.785
