1. Cheetahs can accelerate to a speed of 20.0 m/s in 2.50 s and can continue to accelerate to reach a top speed of 27.6 m/s. Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +?+x direction point in the direction the cheetah runs. Express the cheetah's top speed ?top in miles per hour (mi/h)(mi/h) . vtop = Starting from a crouched position, how much time ?accel does it take a cheetah...

In a 4 km fun run, a person runs at a constant speed of 4.20 m/s over the first 2 km (let's call this period A), and then walks at speed 1.00 m/s for a period of 2 minutes (120 seconds, let's call this period B), and then completes the fun run at a constant speed of 3.00 m/s during the final period C a. Draw a position time graph for this run, labelling the periods A, B and C...
