<span>Assuming the mass of the container holding the 4 blocks is negligible, we are attempting to accelerate 4 times the mass (which would decrease acceleration by a factor of 4) with 2 times the force (which would increase acceleration by a factor of 2). So the resulting change in acceleration will be 1/4 * 2 = 1/2 as much as the original situation. And since the original situation was an acceleration of 1 m/s^2, the situation with 2 newtons of force and 4 blocks will be 0.5 m/s^2.</span>
Answer:
Workdone = 6000Nm
Explanation:
Given the following data;
Mass = 5kg
Force = 500N
Distance = 12m
To find the work done;
Workdone = force * distance
Workdone = 500 * 12
Workdone = 6000Nm
Answer:
Explanation:
We can use Newton's Universal Law of Gravitation to solve this:
, where is force, is gravitational constant , and represent the masses of both objects, and represents the distance between their center of masses.
Plugging in our given values, we have:
(one significant figure).
