I don't know what to do for these three questions and they're due on Wednesday
a. A sprinter can accelerate with constant acceleration for 2.28s before reaching top speed.
He can run 148.0m in 16.6s. What is his speed as he crosses the finish line?
b. A car accelerates at 2.15m/s2 along a straight road.
It passes two marks that are 29.5m apart at times t=3.95s and t=4.85s.
What was the car's velocity at t=0?
c. You've attached a rocket to the rear of a small car
The rocket provides a constant acceleration for 4.68s.
As the rocket shuts off, a parachute opens and slows the car at a rate of 3.43m/s2.
The car passes the judges' box, 878.0m from the starting line, exactly 14.0s after you fire the What is the car's speed as it passes the judges?
I don't even know where to start I'm just too stressed
