4. A cheetah is squatted 25 m to the east of a vehicle. At time t = 0 the cheetah begins to run due east toward an antelope that is 55 m to the east of the vehicle. During the first 2.0 s of the chase, the cheetah's x-coordinate varies with time according to the equation x = 25 m + (4.5 m/s2)t2. (a) Find the cheetah's displacement between ti = 1.5 s and t2 = 3.0 s. (b) Find its average velocity during that interval. (c) Find its instantaneous velocity at t = 2.5 s by taking At = 0.15 s.

A blue car of length 4.52 m is moving north on a roadway (hat intersects another perpendicular roadway (Fig. P2.81, page 58). The width of the intersection from near edge to far edge is 28.0 m. The blue car has a constant acceleration of magnitude 2.10 m/s2 directed south. The time interval required for the nose of the blue car to move from the near (south) edge of the intersection to the north edge of the intersection is 3.10 s. (a) How far is the nose of the blue car from the south edge of the intersection when it stops? (b) For what time interval is any part of the blue car within the boundaries of the intersection? (c) A red car is at rest on the perpendicular intersecting roadway. As the nose of the blue car enters the intersection, the red car starts from rest and accelerates east at 5.60 m/s2. What is the minimum distance from the near (west) edge of the intersection at which the nose of the red car can begin its motion if it is to enter the intersection alter the blue car has entirely left the intersection? (d) II the red car begins its motion at the position given by the answer to pan (c), with what speed does it enter the intersection?
Why is the following situation impossible? A shopper pushing a cart through a market follows directions to the canned goods and moves through a displacement 8.00im down one aisle. He then makes a 90.0 turn and moves 3.00 m along the y axis. He then makes another 90.0 turn and moves 4.00 m along the x axis. Every shopper who follows these directions correctly ends up 5.00 m from the starting point.
As she picks up her riders, a bus driver traverses four successive displacements represented by the expression (6.30 b)i (4.00 b cos 40)i (4.00 b sin 40)j + (3.00 b cos 50)i (3.00 b sin 50)j (5.00 b)j Here b represents one city block, a convenient unit of distance of uniform size; i is east; and j is north. The displacements at 40 and 50 represent travel on roadways in the city that are at these angles to the main east-west and north-south streets, (a) Draw a map of the successive displacements, (b) What total distance did she travel? (c) Compute the magnitude and direction of her total displacement. The logical structure of this problem and of several problems in later chapters was suggested by Alan Van Heuvelen and David Maloney, American Journal of Physics 67(3) 252-256, March 1999.
