What is the KE of a 1 kg ball traveling at 20 meters per second?

1 answer:

3 0

The easiest way to find that answer is to look at the solution that I just gave you for the same ball traveling at 30 M/Sec, and just substitute 20 in place of 30 in that solution.

Step-by-step explanation:

all sides added up, 5+5=10+8=18 now the bottom, since the two sides are both 10 inches we can safely assume the other two will be 10 inches aswell, so 10+10+10+10=40.

Find the volume of the composite solid. Round your answer to the nearest tenth

Vesna [10]

Answer:

V = 1206.3 $ft^{3}$

Step-by-step explanation:

This shape is made up of a cylinder on the bottom and a cone on the top. We'll find the volumes of these shapes separately and then add them together.

Volume of a cylinder = area (of the base) x height

Substitute in the formula for the area of a circle.

V(cylinder) = $\pi$ $r^{2}$ x h

Substitute in the values for the radius (8) and height (4)

V(cylinder) = $\pi$ x $8^{2}$ x 4

Evaluate using a calculator

V(cylinder) = 804.2477

To the nearest tenth, V(cylinder) = 804.2

Volume of a cone = $\frac{\pi r^{2}h }{3}$ . This is the area of the circular part of the cone ( $\pi r^{2}$ ), multiplied by the height from the point to the base, all divided by 3.
