Since energy is always conserved, you can solve problems involving energy transfer. Russell Wilson throws a football straight up into the air. If he throws the ball (with mass .45 kg) with a speed of 25 m/s and there is no air resistance, how high does the football go? Insert a picture of your work (or type it out).
a. Write out the formula for this problem. (2 pts) b. Plug in the values from this problem into the formula. (2 pts)
C. Solve the problem, writing out each step. (2 pts)
d. Correct answer (2 pt)
e. In the real world, there would be air resistance. How will this affect the height the ball reaches and WHY? (2 pts)

(just wanna double check)
if you are able to help, i may give brainliest ​

i had this question and the answer was 3.15 miles.

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.
