(a) Plot a graph of the car's position versus time. x(m) 10 8 6 4 2 0 V -6 Problem 3 A race car moves such that its position fits the relationship * = (5.0 m/s)t + (0.75 m/s) where x is measured in meters and t in seconds. Find the instantaneous velocity at the instants (a) t=1.00 s, (b) t-3.00 s, (c) t=4.50 s, and (d) t-7.50 s. If a particular car covers the first half of the track at an average speed of 230 km/h, what minimum average speed must it have in the second half of the event in order to qualify Problem 2 This is the graph of position versus time for a certain particle moving along the x-axis. Transcribed image text: Problem 1 A qualification for a racing event, an F1 race care must have the average speed of 250 km/h on track with 1,600 meters length.
