Question

1. the finish line is 100m away from the starting line, you manage to get there in 4 seconds (10 seconds faster than your friend) what was your average velocity during the race?

for this question the net force on you is 100N upwards after bouncing on a trampoline, using mass (your weight (150 pounds)/2) get your mass in kg



now that you have mass what is your acceleration upwards based on the net force and your mass?

Answer 1

1) V = 100/4 = 25 m/s

2) Fn = 100N, Fg = 75*9.81

Sum force Y = ma

100 - 735.75 = 75a

a = -8.48 m/s^2
