Answer:
The answer to the question is
A 100 lb person would weigh 300.33 lbf at the upper atmosphere of Jupiter
Explanation:
To solve the question we note that
Mass of object = 100 lb = 45.35924 kg
Mass of Jupiter = 300×Mass of Earth = 300×5.972 × 10²⁴ kg =1.7916×10²⁷ kg
Radius of Jupiter = 10× Radius of Earth = 10×6,371 km = 63710 km
Gravitational constant, G = 6.67408 × 10⁻¹¹ m³ kg-1 s-2
Gravitational force is given by
Plugging in the values we get
=
= 1335.93 N
Converting into lbf gives 1335.93 N *0.2248 lbf/N = 300.33 lbf
Answer:
The tension in the tow rope pulling the log is 784.61 N
Explanation:
Given:
v = speed = 13 m/s
Pf = final power when the log is pulled = 8.5x10⁴W
Pi = average power = 7.48x10⁴W
The force required to move a car is equal to:
T = Ff - Fi = 6538.46 - 5753.85 = 784.61 N
