Take right to be the positive direction for this question.  A car is moving to the left at decreasing speed.  What are the signs of the car’s velocity and acceleration?

[Be sure to show all work.  When doing calculations, start with the symbolic equation(s) from the equation sheet, written down just as they are on the equation sheet and then progressing from there to a solution.] A plane lands on a runway and travels for 1.50 s at a constant speed of 88.0 m/s before the pilot begins to slow the plane down at a constant rate of 5.00 m/s2.  a) Draw a motion diagram that represents all of the plane’s time on the runway.  [You will upload this at the end of the exam.] b) Will the plane still be moving when it gets to the end of the 800-m long runway? [Enter your answer below and upload your written out calculations and explanation after the exam.] c) If the plane is still moving at the end of the runway, calculate what the minimum acceleration would need to have been to get the plane to stop in time.  If the plane was not moving at the end of the runway, calculate how much extra runway space it had. [Enter your answer below and upload your written out calculations after the exam.]
