Answer:
0.3950m
Explanation:
Use conservation of angular momentum:
Let L be the angular momentum(a vector).
We know that:
and that the two masses have the same radius:

Hence, the weights are 0.3950m away .
Explanation:
average speed is the total distance divided by total time
Work = force * distance.
<span>You must produce twice as much energy as we are lifting the weight twice as high. </span>
<span>But because you aren't increasing the force, you need to increase the length of the ramp instead. </span>
<span>The new length will be twice as great as the previous length. </span>
<span>So 8 metres is required. </span>
Hope this helps.
Answer:
A roller coasters accelerates from an initial velocity of of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration? Q. Acceleration only takes place when things speed up. Q. A drag racer accelerated from 0 m/s to 200 m/s in 5 s.
