- A cyclist coasts up a 10.7 degrees slope, traveling 24.0 m along the road to the top of the hill. If the cyclist's initial speed is 9.70 m/s, what is the final speed? Ignore friction and air resistance.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. mThe 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?
- 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. _____________ mThe skateboarder in the drawing 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?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.

As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.286 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing.You ski straight down a 40.6 degree slope, starting from rest and traveling a distance of 11.3m along the slope . Find your final velocity, assuming negligible air resistance and friction?
