i didn't understand uhage567 said:It's wrong.
You must consider the energy he has at the top of the hill. Apply conservation of energy between that height and the height of the jump.
can u give me proof?hage567 said:Well for one thing, the kinetic energy the skier has at the time he reaches the jump must come from somewhere. The change in potential energy between the top of the hill and the jump is what will determine the kinetic energy at the jump. It will determine his velocity.
Why don't you think the potential energy the skier has at the top of the hill is important in finding out how much kinetic energy he has at the jump?

You have not shown any reasoning for your answer.
Well you must have done your answer that way for some reason.because i am not sure about my answer
What kind of proof are you looking for? I'm not going to give you the answer if that's what you mean.can u give me proof?

Have you tried to use my idea to solve this problem? What about it is giving you trouble?
Can you find the total energy of the skier when he is at rest at the top of the hill?
The formula for calculating the velocity of a skier jumper after jumping a 105 m hill is v = √(2gh), where v is the velocity in m/s, g is the acceleration due to gravity (9.8 m/s²), and h is the height of the hill in meters.
Based on the formula v = √(2gh), the velocity gained by a 84 kg skier after jumping a 105 m hill would be approximately 53.5 m/s.
Yes, the velocity of a skier jumper is affected by their weight. According to the formula v = √(2gh), the velocity is directly proportional to the square root of the height and inversely proportional to the square root of the weight. This means that a heavier skier would have a slightly lower velocity compared to a lighter skier jumping from the same height.
Yes, the velocity of a skier jumper is affected by air resistance. As the skier moves through the air, they experience air resistance which acts in the opposite direction of their motion. This resistance can decrease the velocity of the skier jumper, making them land at a slower speed than expected.
The velocity of a skier jumper can greatly affect their landing. A higher velocity can result in a longer jump, but it also means a faster and potentially harder landing. A lower velocity can result in a shorter jump, but it also means a slower and potentially softer landing. It is important for skier jumpers to carefully control their velocity to ensure a safe and successful landing.
