The figure shows the speedometer readings as a car drives down a straight road. (attached) a. What is the acceleration at t = 8.0s. b. What is the change in the cars speed from 5-10 seconds? c. What distance is traveled by the car between t = 0 and t = 4 s d. Draw a graph of the acceleration for the cars motion between t=0s and t=14s

1. Consider the following v-t graph. a. At what time(s) is the object moving fastest? What is its speed at that time(s)? b. c. Draw a matching d-t graph. d. How far did the object move during the first 5 seconds? e. How far did the object move during the first 10 seconds? √(5) O 0 IT N + 6 4 1 T 00 O IN 2 IT -lot *LD O • [] 4 20 t(o)

A. using your measured distance (35 inches) your average time of motion (drop times 2.04s,1.78,2.26,1.59,1.87 and 1.91)and the constant acceleration equation (x=1/2 at^2)calculate the acceration of the atwood machine. B. using m2-m2/m1+m2(9.8)=20/40=0.5x9.8=4.9 and the masses (60,70g) calculate the expected acceleration. C. what quanatiative compariosn is most appropriate between your results (percent difference or error)?

Lucas is driving west with belongings on car. After driving west for an hour and a half he stops for gas 110 km from his parents house.As he gets back in car he notices one of the boxes fell off. He gets back in car and heads east for 30 minutes traveling 50 km before he sees box.Determine Luca average speed and velocity for each part of the trip.a. The first hour and a half B. The next 20 minutes. Did he travel faster or slower compared to the 1st hour and half? C. The whole trip
