Plz help i will give 1. A popular sprinter of mass 60 kg, was running a 100 m race. Her velocity was measured over a 10.0 s period. The results are recorded in Table 1.

Velocity, v/ms^-1 0.0 2.5 5.0 7.5 10.0 10.0

Time, t/s 0.0 2.0 4.0 6.0 8.0 10.0

a. Use the results from Table 1 to plot a graph of Velocity versus Time on a graph paper.
b. Determine the slope of the graph over the first 6.0 s of the race.
c. What quantity does the slope of the graph represent?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
