6. (6P) Formula Based Problem: A car is speeding down a highway at 30 m/s. A stray dog
runs into the road ahead of the driver. The driver hits the brake decelerating at a rate of
10m/s. The driver managed to stop the car right as it was about to hit the car. How far
away was the dog when the driver first hit the brake?
Formulas: v=at+v.
x=+at+v. t
7. (8P) Formula Based Problem: A baseball player hits a ball at a Vox of 20m/s and a Voy of

resistance
Formulas: v. =ą, t+Vox x=yzą, t+vt
x=12a, t+vot
Vy=a, t+v

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
