Use the exact values you enter to make later calculations.
A uniformly accelerated car passes three equally spaced traffic
signs. The signs are separated by a distance d = 21 m. The
car passes the first sign at t = 1.3 s, the second sign at
t = 3.7 s, and the third sign at t = 5.5 s.
(a) What is the magnitude of the average velocity of the car
during the time that it is moving between the first two
signs?
(b) What is the magnitude of the average velocity of the car during
the time that it is moving between the second and third
signs?
(c) What is the magnitude of the acceleration of the car?

An initially motionless test car is accelerated uniformly to 105 km/h in 8.03 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.455 seconds, after which the car is measured to be traveling at 87.5 km/h. What is the magnitude of the acceleration of the car before the collision? Number m/s What is the magnitude of the average acceleration of the car during the collision? Number m/s What is the magnitude of the...
