1) A car is cheating in a race and is starting at = 16
over at tr=2.3s and the car has a final velocity y = 45
end of the race? (assume all motion is on the x-axis)
Fa
when the race starts (to=0s). The race is

2) A meteor is falling to earth and enters the Earth's atmosphere at = -435, if it
experiences an acceleration due to Earth's gravity of a = -9.8ŷ, how what will its velocity be
after t= 13s? (assume all motion is vertical, which means on the y-axis. You will use y for up, and
-ý for down)
3) A jet is landing and touches down on the runway. It has an initial velocity = 509X; The
breaks apply an acceleration of a = -19.6 for period of t=2.1s, how far does the jet
displace from the point of touch down (xo = Om) during this time?
4) A shark is swimming slowly until it sees a fish at xo = 3.14 m. The shark's initial velocity is =
42. It accelerates at a = 4.2, and catches the fish at xy = 15.6m. What is its final velocity
after it catches the fish?
