How many joules of gravitational potential energy does a person have after they went up stairs that are 10 meters tall? Assume t
he person has a mass of 60 kilograms. And assume this takes place on earth.
1 answer:
9514 1404 393
Answer:
5880 J
Step-by-step explanation:
PE = mgh = (60 kg)(9.8 m/s²)(10 m) = 5880 J

Speed = distance / time
30 = d / 2.5
30 * 2.5 = d
75 = d
40 = d / 1.875
40 * 1.875 = d
75 = d
50 = d / 1.5
50 * 1.5 = d
75 = d
60 = d / 1.25
60 * 1.25 = d
75 = d
24 = 75 / time
time = 75/24
time = 3.125 hours
42/51 = 14/17
14/17 x 100 = 82.35294
=82.4%
280=100%
210=x% ( cross multiply)
280X=21000
X=75%
