Answer:
Explanation:
PE = mgh = 2.0(9.8)(1.2) = 23.52 ≈ 24 J
Translation kinetic energy is defined as the energy of a system due to the motion of the system’s...center of mass
KE = ½mv² = ½(45)(1800/600)² = 202.5 ≈ 203 J
Answer:
d is the correct answer for this question hope it helps
Explanation:
when you see a A in a circle the the ammeter
1 millimetre is 0.001 metre.
1 metre is 1,000 millimetres.
He has a mass of 56 kg.
The equation given is PE = mgh.
PE = 4620 J
h = 8.4
g = 9.8
Therefore:
4620 = 82.32m
m = 4620/82.32
m = 56 (rounded to two significant digits)
