I have to make a graph showing to the tenth of a second showing velocity, displacement, and acceleration for throwing a tennis ball up three times and letting it hit the ground. My times are 2.85 seconds, 2.56 seconds, and 2.60 seconds.

Any help would be greatly appreciated.

So what is the problem? You have equations to let you compute v, d, and a vs time.

please i need a help in this question.

1.the effective mass of the holes in a particular intrinsic semiconductor is four times that of the electrons. the band gap is 1 eV . calculate the temperature at whcih the fermi level would be shifted by 10% from the middle of the band gap.

To create a graph showing velocity, displacement, and acceleration for throwing a tennis ball up and letting it hit the ground, you'll need to follow these steps:

Step 1: Determine the time intervals
Since you want to show velocity, displacement, and acceleration to the tenth of a second, you need to break down the time intervals accordingly. In your case, you have three time intervals: 2.85 seconds, 2.56 seconds, and 2.60 seconds. To analyze the motion more accurately, it's better to break the time intervals into smaller segments. Let's break each time interval into 0.1-second segments.

Step 2: Calculate velocity
Velocity represents the rate of change of displacement with respect to time. Since you're analyzing the motion of a ball being thrown up and then falling back down, the velocity will change twice in each time interval. For simplicity, we will consider the ball's initial velocity as 0.

To calculate the velocity, you need to calculate the change in displacement and divide it by the corresponding time interval. The velocity at any given moment can be represented as Δd/Δt, where Δd represents the change in displacement, and Δt represents the change in time.

Step 3: Calculate displacement
Displacement represents the change in position or location of an object. In this case, the displacement of the ball can be positive when it is thrown up and negative when it falls back down.

To calculate displacement, you need to consider the ball's initial position, the distance it traveled when thrown up, and the distance it traveled when falling back down.

Step 4: Calculate acceleration
Acceleration represents the rate of change of velocity with respect to time. Since the velocity of the ball changes twice in each time interval, calculating acceleration requires considering the change in velocity and dividing it by the corresponding time interval. The acceleration at any given moment can be represented as Δv/Δt, where Δv represents the change in velocity, and Δt represents the change in time.

Step 5: Plotting the graph
Once you have calculated the velocity, displacement, and acceleration for each time interval, you can plot them on a graph. On the x-axis, you will have the time intervals (in seconds) broken down into 0.1-second segments. On the y-axis, you will have the respective values for velocity, displacement, and acceleration.

For each time segment, plot the corresponding velocity, displacement, and acceleration values on the graph. Connect the plotted points with a smooth curve to visualize the variations over time.

Remember to label your axes and provide a title to your graph to make it clear and informative.

By following these steps, you should be able to create a graph showing velocity, displacement, and acceleration for throwing a tennis ball up and letting it hit the ground.
