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?
You ski straight down a 42.0 degrees slope, starting from rest and traveling a distance of 10.3 m along the slope. Find your final velocity, assuming negligible air resistance and friction.
From approximately what floor of a building must a car be droppedfrom an at-rest position so that it reaches a speed of 80.7 ft/sec whenit hits the ground? Each floor is 12ft higher than the one below it.
