Answer:

I will show u

Explanation:

F=mg

F=GMm÷r(square)

Therefore mg=GMm÷r(square)

S all m on both sides will be cut.

Therefore mass of a free falling body is useless.

Question 18
Sedaia [141]

Answer:

5.5 kg

Explanation:

The gravitational potential energy of an object is given by

U=mgh

where

m is its mass

g is the acceleration of gravity

h is the height of the object above the ground

For the rock in the problem, we know:

h = 12 m is the height above the ground

U = 650 J

g = 9.8 m/s^2

Therefore, we can solve the equation for m, the mass of the rock:

m=\frac{U}{gh}=\frac{650}{(9.8)(12)}=5.5 kg

Olegator [25]
Using Dimensional analysis
15min/1·1hr/60min
15/1·1hr/60=15/60hr
.25hr
.25hr·12.5Km/h=3.125Km
