How do you calculate height after bounce?
Between the first and second bounces, the height can be expressed as h = 140 − 16(t − 6.49)2, 3.54 ≤ t < 9.45. The 6.49 is when the highest point is achieved (halfway between the two bounces), and the 9.45 seconds is derived from adding 3.54 seconds to the time between the first and second bounces.
How do you find the velocity of a ball after bounce?
3 Answers
- While the ball is not in contact with the ground, the height at time t after the last bounce at t0 is given by h(t+t0)=v0t−12gt2. where v0 is the velocity just after the bounce.
- During the impact, the ball will deform and there will be friction.
How do you find the coefficient of restitution of a bouncing ball?
Analysis. Coefficient of Restitution = speed up/speed down. Where v = velocity, g = 9.8m/s2, and h = average height measured. We took the average of the bounced height value (h) and put it in the formula along with the initial height (H) of 92 cm.
What is the height of a bouncy ball?
Height balls bounced: soccer ball: 62 cm. tennis ball: 41 cm. exercise ball: 65 cm.
Is the height of a balls bounce affected by the height from which the ball is dropped variables?
Hypothesis: If a tennis ball is dropped from a specific height then the ball will bounce to the same height. Independent Variable: The height from which the ball is dropped….Data Table 2: Average Bounce Height at Each Height:
| Drop Height (cm) | Average Bounce Height (cm) |
|---|---|
| 80 | 40. |
| 100 | 51 |
How does the size of a ball affect its bounce?
The size of the ball can affect its bounce due to air resistance, surface volume and density. However, mass can also play a part in how a ball bounces. If two balls contain the same mass, but are of different sizes, the larger ball will bounce less due to greater air friction against its surface.
How do you calculate restitution?
Subtract any payments made by the defendant from the total amount of gain bestowed on the defendant. Here, restitution damages would equal $7,000 because the shipment total was $10,000 and the defendant paid $3,000 to the plaintiff.
What is coefficient restitution?
Definition of coefficient of restitution : the ratio of the relative velocity of two elastic bodies after rebounding to velocity before impact.
How do you calculate bounce height for multiple bounces?
For multiple bounces, it’s just like dropping the ball again from a reduced height. If the first height is h, the second will be f*h, the third f*f*h, the fourth f*f*f*h, and so on. So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on.
How do you make a basketball bounce off the wall?
Tape the butcher paper along the floor and up the wall so that when the ball bounces the paint will stay on the wall at the spot where the ball hits. (See picture.) Paint each of the balls with poster paint in a circle around the ball so that you can hold the ball on both sides to bounce it. Stand 1 meter from the wall.
Which ball will bounce the highest?
They chose a tennis ball, a soccer ball, and an exercise ball. Which ball will bounce the highest, a tennis ball, an exercise ball, or a soccer ball? The exercise ball will bounce the highest. Tape the butcher paper along the floor and up the wall so that when the ball bounces the paint will stay on the wall at the spot where the ball hits.
How do you Bounce a basketball without hitting the ball?
Paint each of the balls with poster paint in a circle around the ball so that you can hold the ball on both sides to bounce it. Stand 1 meter from the wall. Measure this distance using a meterstick. Bounce each ball toward the wall without using any of your own force.
