The mass of the second object is
Explanation:
The magnitude of the gravitational force between two objects is given by :
where :
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them objects
In this problem we have:
F = 1100 N is the force
is the mass of object 1
r = 30 m is the distance between the object
Re-arranging the equation for , we find the mass of the second object:

The constant force applied to the rope is 7.72 N.
<h3>Net torque on the drum</h3>The net torque on the drum is calculated as follows;
Linear speed, v = ωr = 23 x 0.4 = 9.2 m/s
distance traveled = 14 m
<h3>Tangential acceleration</h3>The acceleration of the drum is calculated as follows;
v² = u² + 2as
v² = 0 + 2as
v² = 2as
a = v²/2s
a = (9.2)/2(14)
a = 0.329 m/s²
<h3>Angular acceleration of the drum</h3>The constant force applied to the rope is calculated as follows;
