Part C Now, observe the graphs of the horizontal and vertical components of velocity versus time:
• On the graph of x vs. t, click the x and from the drop-down list, select Vx.
• To display the graph of vy vs. Í repeat step 1, using the graph of y vs. t.
What do you observe about the velocity components of the snowboarder before and after time t = 0

This is for Plato

While strolling downtown on a saturday afternoon, you stumble across an old car show. as you are walking along an alley toward a main street, you glimpse a particularly stylish alpha romeo pass by. tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. thinking back to your physics class, you realize that you can calculate the car's acceleration. you estimate the width of the alleyway between the two buildings to be 6 m. the car was in view for 0.6 s. you also heard the engine rev when the car started from a red light, so you know the alpha romeo started from rest 4 s before you first saw it. find the magnitude of its acceleration.
