A 74.0 kilogram skateboarder launches off a ramp with an initial speed of 7.35 meters per second. The skateboarder lands at a location which is a vertical distance of 2.50 meters below the top of the ramp. If there was no drag or friction, then what would be the speed of the skateboarder just before landing? If the skateboarder's actual speed just before landing is 9.25 meters per second, then how much thermal energy was generated?

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
