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 6.37×103km . How many meters lower will its surface be 32.0 km from the ship along a horizontal line parallel to the surface at the ship?  Does your answer imply that error introduced by the assumption of a flat Earth in projectile motion is significant here?

A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a ramp of 61.8 degrees at a speed of 49 m/s. What would be the largest number of buses he can clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 10.0 m long? Use g = 9.8 m/s?. Your answer should be in the form of an integer number (e.g., 3 buses, not 3.4 buses).

A space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y  components.

A projectile is fired from the ground level at an initial angle of 80° above the horizontal and travels 14 meters away (horizontal distance) from its starting position. (t is measured in seconds.) (a) Calculate its initial speed. Round your answer to the nearest tenth. (b) Calculate its maximum height above the ground level. Round your answer to the nearest tenth.

The 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.

Based on a grade 11 physics student, answer the following question: A poké-ball rolls off Ash’s table with a velocity of 1.93 m/s [horizontally].  The tabletop is 76.5 cm above the floor.  If air resistance is negligible, determine  how long the poké-ball is airborne the horizontal range (distance) the velocity at impact

A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a ramp of 27.7 degrees at a speed of 42.3 m/s. What would be the largest number of buses he can clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 10.0 m long? Use g = 9.8 m/s?. Your answer should be in the form of an integer number (e.g., 3 buses, not 3.4 buses).

A rodeo horse is running around a corral at a speed of 300 ft/s. Let x(t) be the distance of the horse from the third barrel and y(t) his distance from the fourth. (see figure; note that the distance between barrels is 900 řt). At what rate is the horse's distance from the fourth barrel changing at the instant when he is 200 ft from the third? 2 1 3 4

At a football game, imagine the line of scrimmage is the y-axis. A player, starting at the y-axis, runs 8.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction). He then throws the football straight downfield 55.0 yards in a direction perpendicular to the y-axis (in the +x-direction). What is the magnitude of the displacement (in yards) of the ball?  yards (b) What if? The receiver that catches the football travels 64.0 additional yards at an angle of 45.0° counterclockwise from the +x-axis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run?

A bullet is fired from ground level at 264 m/s and at an angle of 30.0°. Neglecting air resistance, answer the following questions: (a) What is the initial horizontal component of the velocity? Vix (b) What is the initial vertical component of the velocity? V₁y = (c) How high will the bullet rise? dymax m/s m/s Remember to round your answers to the correct number of significant digits.
