Answer:
it will show a continuous rise in value. The rise will be sinusoidal.
Explanation:
The forces (what causes the ball to accelerate) are gravity, friction, and the normal force. In this case, gravity is a downward force caused by the gigantic mass of the Earth and the mass of the ball. Keep in mind that a force is acceleration. Acceleration is a change in velocity. The ball speeds up. Than it stops speeding up at a certain point where the frictional force (along with air friction) equals the parallel component of gravity.
Newton's Second Law States- The greater mass of an object, the more force it will take to accelerate the object.
Answer:
q = -1.61x10⁻¹⁷ C
Explanation:
The charge of the particle can be found using the definition of the work done by electric force:
(1)
<u>Where</u>:
q: is the charge
ΔV: is the difference in electric potential
The work is also equal to:
(2)
<u>Where</u>:
and 
are the electric potential energy of the points A and B, respectively.
Now, by conservation of energy we have:
(3)
<u>Where</u>:
and 
are the kinetic energy of the points A and B, respectively.
Rearranging equation (3):
Solving the above equation for q:
Therefore, the charge of the particle is -1.61x10⁻¹⁷ C.
I hope it helps you!
The kinetic energy of any moving object is
(1/2) (mass) (speed²) .
For the object you described, that's
(1/2) (100 kg) (12.5 m/s)²
= (50 kg) (156.25 m²/s²)
= 7,812.5 joules
