You can visualize the process if you think about a trip in your car. if you tell a friend that you are 140 miles away from your starting point and traveled at 70 miles per hour, your friend would know you had been traveling 2 hours. you know this from the relationship: distance (d) - velocity (v) * time (t) d=v. t or t=d/ (eq. 3) question 12. we can now determine when the universe "started its trip." use the distance and velocity of one of the galaxies and eq 3. finally, convert your answer to billions of years (show your work and conversion, with units). confirm that this answer is roughly in range of your answer to question 5.18 pts age (seconds) = age (years) = billion yrs

While strolling downtown on a saturday afternoon, you stumble across an old car show. as you are walking along an alley toward a main street, you glimpse a particularly stylish alpha romeo pass by. tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. thinking back to your physics class, you realize that you can calculate the car's acceleration. you estimate the width of the alleyway between the two buildings to be 6 m. the car was in view for 0.6 s. you also heard the engine rev when the car started from a red light, so you know the alpha romeo started from rest 4 s before you first saw it. find the magnitude of its acceleration.
