I think the answer is "<span>The ball that went out of the park shows more work because the distance was greater."</span>
6.84m
Explanation:
According to this formula
<span>speed of wave=wavelength×frequency</span>
you have
<span>wavelength=<span>speedfrequency</span>=<span><span>342 m<span>s<span>−1</span></span></span><span>50<span>s<span>−1</span></span></span></span>=<span>6.84 m</span></span>
Answer:
Not 100% sure but if I'm right its 15 min.
Explanation: 1 mile is equal to 5380 feet, 26400 ÷ 5380 = 5, 75 ÷ 5 = 15
Answer:
1.6 m/s2
Explanation:
Let
be the gravitational acceleration of the moon. We know that due to the law of energy conservation, kinetic energy (and speed) of the rock when being thrown upwards from the surface and when it returns to the surface is the same. Given that
stays constant, we can conclude that the time it takes to reach its highest point, aka 0 velocity, is the same as the time it takes to fall down from that point to the surface, which is half of the total time, or 4 / 2 = 2 seconds.
So essentially it takes 2s to decelerate from 3.2 m/s to 0. We can use this information to calculate 

So the gravitational acceleration on the Moon is 1.6 m/s2
Answer:
3 m/s
^2 rounded to one signifiicant figure.
