You drive a go-cart around a track as shown below, consisting of two arcs connected by two straightaways as shown. The radius of the larger arc is 30 meters, and the radius of the smaller arc is 10 meters. 1. You drive at a constant 7.0 m/s clockwise around the track. Draw an arrow indicating the direction of a at points W, X, Y, and Z. Draw the arrows so a larger acceleration gets a longer arrow. Write "a = 0" if the acceleration is zero at Y that point. Calculate the magnitude of the accelerations at point W and Y. Start with the symbolic equation and show the numbers you used. W: Y:

You drive 7.50 km in a straight line in a direction 25° East of North. a. Find the distances (in km) you would have to drive straight East and then straight North to arrive at the same point. (This is equivalent to finding the components of the displacement along the East and North directions.) b. Show that you still arrive at the same point if the East and North legs are reversed in order.

The problem relates to the gliding flight of flying squirrels. These squirrels glide from tree to tree at a constant speed, moving in a straight line tipped below the vertical and steadily losing altitude as they move forward. Short and long glides have different profiles. A squirrel in a typical long glide covers a horizontal distance of 16 m while losing 8.0 m of elevation. During this glide,a. What is the angle of the squirrel’s path below the horizontal?b. What is the total distance covered by the squirrel?
