Question 15 10 points Save Answer What!! We've gone through an entire homework set without doing an actual physics problem Okay, let's do one simplified problem for the high jump. (The problem isn't that simple, we're just using a very simplified model.) lf a 65 kg high jumper converts all her kinetic energy into potential energy for her jump of 2.3 m, how fast was she going at take off? Hint; 1/2mvn2 -mgh g 9.8 m/sn2 and h 2.3 meters. Cancel the masses do some 9th-grade algebra and viola! You got it!

Explanation / Answer

0.5*65*v^2 = 65*9.8*2.3

v = sqrt(2*9.8*2.3)

v = 6.71 m/s
