Would that be 10?
.1 second per revolution, so 10 rps
B. Remains constant
hope this helps
Answer:
<u>Velocity impact is 50.86 m/s.</u>
Explanation:
If an "object of mass" "m" is dropped from "height" "h", then the "velocity" just before impact is "v" . The "kinetic energy" before impact is equal to its "gravitational potential energy" at the height from which it was dropped: Kinetic energy = J.
![\mathrm{v}^{2}=2 \mathrm{gh}](https://tex.z-dn.net/?f=%5Cmathrm%7Bv%7D%5E%7B2%7D%3D2%20%5Cmathrm%7Bgh%7D)
V is impact velocity
h height in meter = 132 m
![\text { (gis referred to as the acceleration of gravity. Its value is } 9.8 \mathrm{m} / \mathrm{s}^{2} \text { on Earth }](https://tex.z-dn.net/?f=%5Ctext%20%7B%20%28gis%20referred%20to%20as%20the%20acceleration%20of%20gravity.%20Its%20value%20is%20%7D%209.8%20%5Cmathrm%7Bm%7D%20%2F%20%5Cmathrm%7Bs%7D%5E%7B2%7D%20%5Ctext%20%7B%20on%20Earth%20%7D)
![\mathrm{V}^{2}=2 \times 9.8 \times 132](https://tex.z-dn.net/?f=%5Cmathrm%7BV%7D%5E%7B2%7D%3D2%20%5Ctimes%209.8%20%5Ctimes%20132)
![V^{2}=19.6 \times 132](https://tex.z-dn.net/?f=V%5E%7B2%7D%3D19.6%20%5Ctimes%20132)
![V^{2}=2587.2](https://tex.z-dn.net/?f=V%5E%7B2%7D%3D2587.2)
![V=\sqrt{2587.2}](https://tex.z-dn.net/?f=V%3D%5Csqrt%7B2587.2%7D)
V = 50.86 m/s
<u>Velocity impact is 50.86 m/s</u>.
