- A ski jumper starts from rest 47.5 m above the ground on a frictionless track and flies off the track at an angle of 45.0° above the horizontal and at a height of 18.0 m above the ground. Neglect air resistance. (a) What is her speed when she leaves the track? m/s(b) What is the maximum altitude she attains after leaving the track? m(c) Where does she land relative to the end of the track? mA pebble rolls off the roof of Science Hall and falls vertically. Just before it reaches the ground, the pebble's speed is 17 m/s. Neglect air resistance and determine the height of Science Hall.An attacker at the base of a castle wall 3.75 m high throws a rock straight up with speed 7.50 m/s from a height of 1.60 m above the ground. (a) Will the rock reach the top of the wall? Yes No (b) If so, what is its speed at the top? If not, what initial speed must it have to reach the top? m/s Enter a number. (c) Find the change in speed of a rock thrown straight down from the top of the wall at an initial speed of 7.50 m/s and moving between the same two points. m/s (d) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upward between the same elevations? Yes No (e) Explain physically why it does or does not agree.
- You are throwing an egg straight down from the roof of a building at a speed of 13.6 m/s. The building has a height of 37.9 m. Ignoring air resistance, at what speed does the egg hits the ground?An attacker at the base of a castle wall 4 m high throws a rock straight up with speed 7.5 m/s from a height of 1.5 m above the ground. (a) Will the rock exceed the top of the wall? (b) If so, what is its speed when it reaches the top of the wall?An object is thrown with an initial speed of 15 m/s at an angle of 35.0 degrees above the horizontal from the top of a 30.0-m-tall tower. Assume air resistance is negligible, and g = 9.8 m/s2. What is the speed of the object as it hits the ground?
- A ball is dropped (from rest) from a window and hits the ground with a speed of 7.0m/s. If the ball were dropped from double the height, what would be its speed (in m/s) when it hits the ground? Your Answer:The drawing shows a skateboarder moving at 7.40 m/s along a horizontal section of a track that is slanted upward by θ = 47.0° above the horizontal at its end, which is 0.510 m above the ground. When she leaves the track, she follows the characteristic path of projectile motion. Ignoring friction and air resistance, find the maximum height H to which she rises above the end of the track.A slingshot fires a pebble from the top of a building at a speed of 13.0 m/s. The building is 35.0 m talI. Ignoring air resistance, find the speed with which the pebble strikes the ground when the pebble is fired (a) horizontally, (b) vertically straight up, and (c) vertically straight down.
