Help with the Following

A particle moves along the x axis. Its position (measured in meters from the origin) varies with time t (measured in seconds) as in the following equation: xa)=5+a :20 a. What is the initial position of the particle? . What is the position of the particle at t = 7 s. For a. and b. Show your working c. Use GeoGebra to plot the corresponding graph and nd the velocity (the rate at which the position is changing) at t = 7 s. Show the plot and the velocity in your submission d. Use GeoGebra to plot the corresponding graph and find the average velocity in the interval 1 5 t 5 5. Show the plot and the average velocity in vaur Submission A particle moves along the x axis. Its velocity (measured in meters per second) varies with time i: (measured in seconds) as In the following equation: v(t)=3+'a't2 :20 a. What Is the Initial velocity of the particle? b. What Is the velocity at t = 5 s? For a. and b. Show your working c. Use GeoGebra to plot the corresponding graph and nd the displacement {the change in position) the particle undergoes in the time interval 0 S t S 5. Show the plot and the displacement in your submission
