The cannon on a battleship can fire a shell a maximum distance of 32.0 km. (a) Calculate the initial velocity of the shell. (b) What maximum height does it reach? (At its highest, the shell is above 60% of the atmosphere—but air resistance is not really negligible as assumed to make this problem easier.) (c) The ocean is not flat, because the Earth is curved. Assume that the radius of the Earth is

- Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .arrow_forwardA rotating fan completes 1200 revolutions every minute. Consider the tip of a blade, at a radius of 0.15 m. (a) Through what distance does the tip move in one revolution? What are (b) the tip’s speed and (c) the magnitude of its acceleration? (d) What is the period of the motion?arrow_forwardProblem 9: What is the maximum width, w, of the gorge (in meters) so that the agent clears it? w = ______arrow_forward
- A stunt car leaves a 15° upward ramp at 35. The car jumps over a ravine and lands on the other side at 5 m S below the height from which it was launched. a) What is the maximum width of the ravine? (Answer: 77.5 m) b) What is the impact velocity of the car in magnitude and angle? (Answer: 36@21° below x)arrow_forwardAn object is thrown off the top of a 42 m tall building with a velocity of 475 m/s at an angle of 10.4° with respect to the horizontal. (a) How long is the object in the air in seconds? (b) What is the maximum height the object reaches above the ground in meters? c) What is the horizontal distance the object covers in meters?arrow_forwardThe Cannon on a battleship can fire a shell a maximum distance of 45.0 km (A)Calculate the initial velocity of the shell. Answer 664.42 m/s (B)what maximum height does it reach? (At its height, the shell is above a substantial part of the atmosphere--but air restance is not really negligible as assumed to make this problem easier) Answer 11300 m (C) The ocean is not flat, since the earth is curved. How many meters lower will it surface be 45 km from the ship along a horizontal line parallel to the surface at the ship? Answer ? M Does your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here? (Select all that apply) *the error could be significant compared to the size of a target *the error is insignificant compared to be distance of travel *the error is significant compared to the distance of travel *the error is insignificant compared to the size of a target.arrow_forward
- In 1939 or 1940, Emanuel Zacchini took his human-cannonball act to an extreme: After being shot from a cannon, he soared over three Ferris wheels and into a net (see the figure). Assume that he is launched with a speed of 26 m/s and at an angle of 50°. (a) Treating him as a particle, calculate his clearance over the first wheel. (b) If he reached maximum height over the middle wheel, by how much did he clear it? (c) How far from the cannon should the net's center have been positioned (neglect air drag)?arrow_forwardProblem 2: In baseball the pitcher will throw baseballs horizontally and to account for gravity, the pitcher will stand upon a raised mound. Take the pitcher's release point to be 1.2m above the ground and they will hit a spot 0.7m above the ground at a distance 20m away. a) Draw ST vs t, sy VS t, Uz VS t,, Vy vs t, a vs t,, and ay vs t, graphs of the baseball's motion b) from Kinematic Equations on the first page Prove that the velocity needed is = 9(Asz)² V24sy symbolically by starting c) If the pitcher was playing on Mars (g = 3.7m/s, negligible air resistance) how fast would they have to pitch?arrow_forwardb) I(1, 0, 0), J(0, 1, 0), and K(0, 0, 1) 6, A helicopter takes off at a ground velocity of 150 km/h.

- On a dare from a friend, you decide to try to jump a canyon using your bicycle as shown in the figure below. We will define a successful jump as one that allows you to just make it to the edge of the canyon on the far side. Ꮎ Yramp Calculate all the following: A custom ramp has been constructed for you which is yo = 29.6 meters high and is tipped an an angle of 0 = 44.7 degrees. The canyon has a width of Xcanyon 106.8 meters.
