It is because gravity is pushing down on the ball
Answer:
$28200
Explanation:
Since 1 year has 12 months, 10 years have 120 months.
If one has to pay $235 a month, in 120 months one has to pay $235 done 120 times, which is the product of both numbers:

Answer:
The length of the boomerang is 0.364 m
Explanation:
The moment of inertia is:

Where
md = 0.05 kg
mh = 0.12 kg
r = d/2 = 0.273/2 = 0.1365 m

The length of the boomerang is:

Answer:


Explanation:
Given that,
Mass of the clock, m = 108 kg
When the clock is not moving, force acting on it, 
For the clock in motion, force acting on it, 
To find,

Solution,
When an object is at rest, the force acting on it is called force due to static friction and if the object is in motion, the force acting on its called force due to kinetic friction.
Let
is the coefficient of static friction. Force is given by :




Let
is the coefficient of kinetic friction. Force is given by :
