Question 1: which of the following graphs is traveling at a constant speed? graph e graph f graph g graph h question 2: which line represents the constant acceleration? a, b, and d a only c only b and d only question 3: the following displacement graph was created from a toy cart's travel around a small track connected to a computer for data graphing. which statement below is true based on the graph? line segment ab is showing the cart travelling at 10 m/s. line segment bc is showing acceleration as the cart is increasing its speed. line segment de is showing the cart is travelling at a constant rate. line segment cd is showing acceleration as the line has a straight increasing slope. question 4: study the two graphs. use your knowledge of speed and velocity to determine if they are representing the motion of the same object and why. no, the speed graph shows an object (1) at a steady speed, (2) slowing down, (3) stopping and rolling back. the velocity graph shows the object (1) speed up (2) slow down, and (3) stop completely. yes, the object moves (1) at a steady rate (2) speeds up (3) stops and then rolls back, slowing down. yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up. no, the speed graph shows an object (1) speeding up and then (2) slowing down. the velocity graph shows the object in (1) constant motion and then (2)stopping.

Acar moving at constant speed in a straight line with the engine providing a driving force equal to the resistive force f. when the engine is switched off, the car is brought to rest in a distance of 100 m by the resistive force. it may be assumed that f is constant during the deceleration. the process is then repeated for the same car with the same initial speed but with a constant resistive force of 0.800 f. how far will the car travel while decelerating? a. 120 m b. 125 m c. 156 m d. 250 m

Apolice car waits in hiding slightly off the highway. a speeding car is spotted by the police car traveling at speed s = 27.6 m/s. at the instant the speeding car passes the police car, the police car accelerates forward from rest at a constant rate of a = 2.16 m/s^2 to catch the speeding car. assume the speeding car maintains its speed. write an expression for the time it takes the police car to reach the speeding car. use the variables from the problem statement in your expression.
