Velocity is displacement/time
(Displacement is the overall change in distance)
So you’ll want to divide 200 by 25, which should give you:
8 m/s
The work done by the electric field is equal to the loss of electric potential energy of the proton in moving from its initial location to its final location:
where
is the proton charge,
and
are the voltages in the final and initial locations. Substituting, we get
Answer:
It will continue moving at a constant speed because no forces are acting on it.
Explanation:
By the second law of Newton, the force is proportional to the acceleration. If there is no force, there is no acceleration. So, when the astronaut turns off the engines, the rocket will have no acceleration which means that the speed will be constant.
Therefore, the answer is:
It will continue moving at a constant speed because no forces are acting on it.
Answer:
28 miles
Explanation:
3,223 meters/day x 14 days = 45,122 meters
1 meter = 3.28 feet
45,122 meters = 148,000 feet
5280 feet = 1 mile
148,000 feet = 28 miles
