The path straight line slanted down. The maximum height hmar of the cannon- 2. The path is a curve which curves down- ball is given by ward. 1. hmar = V3 Vo 3. The path is also a vertical straight line. g 1 v2 4. The path is a curve which curves up- 2. hmar = V2 9 ward . 1 Up 3. hmar = Question 12 2 9 part 1 of 1 10 points 4. hmar = V2 Vo g A ball is thrown from the top of a building upward at an angle of 38 . to the horizontal 5. hmar = 2 vo and with an initial speed of 11 m/s, as in 3 g the figure. The ball is thrown at a height of 6. hmar = 2 - 52 m above the ground and hits the ground g 34.8561 m from the base of the building. 1 Up The acceleration of gravity is 9.8 m/s . 7. hmar 4 g 1 Up 11 m /S 8. hmar = . . 38 V3 g hand height 9. hmar . . . . . .. g . . . . . 10. hmar = 4- vo 52 m Question 10 part 1 of 1 10 points . . . . . . . . ground level Someone in a car going past you at the speed of 50 m/s drops a small rock from a 34.8561 m height of 1.5 m. How far from the point of the drop will the What is the speed of the ball just before it rock hit the ground? The acceleration due to strikes the ground? gravity is 9.8 m/s. Answer in units of m/s. Answer in units of m. Question 13 Question 11 part 1 of 1 10 points part 1 of 1 10 points A particle moving at a velocity of 7.9 m/s If you are standing in a bus that moves at in the positive x direction is given an accel- constant velocity and drop a ball from your eration of 0.9 m/s' in the positive y direction
