What aspect of bouncing balls relates to matter

1 answer:

8 0

Answer: An aspect of the event of various types of balls bouncing off the same floor, being matter is that all the balls consist of matter. They all occupy space and have a form of energy when moved by a force, such as a person. And for energy, like I just said, when they bounce they create energy as they bounce up and down, so if the ball were to hit some other object, it would have an impact on the still object.

The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.

Hope this helps.......... Stay safe and have a Merry Christmas!!!!!!!!!! :D

Answer:

a) 2nd case rate of rotation gives the greater speed for the ball

b) 1534.98 m/s^2

c) 1515.04 m/s^2

Explanation:

(a) v = ωR

when R = 0.60, ω = 8.05×2π

v = 0.60×8.05×2π = 30.34 m/s

Now in 2nd case

when R = 0.90, ω = 6.53×2π

v = 0.90×6.53×2π = 36.92 m/s

6.35 rev/s gives greater speed for the ball.

(b) a = ω^2 R = (8.05×2π)^2 )(0.60) = 1534.98 m/s^2

You decide to travel by car for your holiday visits this year. You leave early in the morning to avoid congestion on the roads.

Answer:

a) d = 182.08 miles

b) $\overline{v} = 54.5 mph$

Explanation:

a) The distance can be found as follows:

$d_{T} = d_{1} + d_{2} + d_{3}$

$d_{T} = v_{1}*t_{1} + v_{2}*t_{2} + v_{3}*t_{3}$

$d_{T} = 67.4 mph*1.70 h + 0*23.4 min + 54.0 mph*1.25 h = 182.08 miles = 292.9 km$

b) The average speed can be calculated using the following equation:

$\overline{v} = \frac{d_{f} - d_{i}}{t_{f} - t_{i}}$

Where "f" is for final and "i" for initial

$\overline{v} = \frac{182.08 miles - 0 miles}{(1.70 h + 23.4 min*\frac{1 h}{60 min} + 1.25 h) - 0 h} = 54.5 mph$

I hope it helps you!

Answer:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

$f = m \times a$
