The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 5.4 m/s. Neglect nonconservative forces, such as friction and air resistance, and find the height h of the highest point reached by the skateboarder on the right side of the ramp. m
A particle, starting from point A in the drawing (the height at A is 3.00 m), is projected down the curved runway. Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 6.39 above the floor before falling back down. Ignoring friction and air resistance, find the speed of the particle at point A.
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 man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 34.5 m/s and has a speed of 32.5 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance. _____________ m
A 2.75 kg box slides UP a smooth (frictionless) 39-degree hill with an initial speed of 18.0 m/s. To what maximum height above the bottom of the hill does the box reach before stopping?
Interactive Solution 6.39 presents a model for solving this problem. A slingshot fires a pebble from the top of a building at a speed of 20.0 m/s. The building is 28.0 m tall. 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.
The skateboarder starts down the left side of the ramp with an initial speed of 6.3 ft/s. If nonconservative forces, such as kinetic friction and air resistance, are negligible, what would be the height "h" of the highest point (in meters) reached by the skateboarder on the right side of the ramp?

Grug is a creature formed from the top of a Burrawang tree, standing ~1.25m tall. One day, Grug climbs a playground slide of 2.9 m height, and slides down its largely frictionless surface. The bottom of the slide is 80 cm above the ground. With what speed does Grug leave the slide? (Units: m/s)

A block slides down a smooth ramp, starting from rest at a height h. When it reaches the bottom it’s moving at speed ν. It then continues to slide up a second smooth ramp. At what height is its speed equal to ν/2?A. h/4 B. h/2 C. 3h/4 D. 2h
A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d = 3.03m. Now suppose the blocks starts on the track at x = 3.11 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 5.59 m/s 4.05 m/s 7.71 m/s 7.91 m/s
