No net force acts on it.example is the earth
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Answer:
-3802 m/s
Explanation:
The y-component of the final velocity is ...
(6598 m/s)·sin(-20.5°) ≈ -2310.7 m/s
The y-component of the velocity due to acceleration is ...
(5200 m/s²)(0.350 s)sin(55°) ≈ 1490.9 m/s
Then the initial velocity in the y-direction is found from ...
initial velocity + change in velocity = final velocity
initial velocity = (final velocity) - (change in velocity)
= -2310.7 m/s - 1490.9 m/s ≈ -3802 m/s
Couloumb's law : (1/(4*pi*epsilon_nought))*((q_1*q_2)/r^2)
8.99*10^9* ((charge of a proton*charge of an electron)/(6.5*10^10m)^2)
8.99*10^9* ((1.602*10^-19)(|-1.602*10^-19|)/((6.5*10^10)^2)
=5.4608*10^-50
