Textbook Question
Chapter 10, Problem 6AP
A Dallas Cowboy carrying the ball straight down the near sideline with a velocity of 8 m/s crosses the 50-yard line at the same time that the last Buffalo Bill who can possibly hope to catch him starts running from the 50-yard line at a point that is 13.7 m from the near sideline. What must the Bill’s velocity be if he is to catch the Cowboy just short of the goal line? (Answer: 8.35 m/s)

The slower rabbits will produce faster offspring than the faster rabbits in the current generation. O b.If your friend selectively breeds her fastest rabbits, you expect the next generation to be significantly faster. OC. The best way to increase running speed in the next generation would be to alter the environment, maybe increasing nutrient density of the food. O d.

They decided to measure the amount of frictional force experienced by the model car and the distance it traveled in meters. The scientists were able to evaluate the frictional work using the following data. Mass (g) Distance (m) Force Work Done by Friction (J) car going up the incline 100 39 0.063 2.457 car going down the incline 70 39 0.2309 ? It is known that the relationship between force and distance determines the work done by friction (W+). W₁ = fd Wf work done by friction f = force d = distance Question: How much work done by friction was exerted on the car as it moved down the inclined plane?
