This Question: 1 pt Skid mark analysis is one way to estimate the speed a car was traveling prior to an accident. The speed, that the vehicle was traveling in mies per hour can be approximated by the formula 330df, where d represents the length of the skid marks in feet and represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling ata speed of 75 mph when it...

function s/x)- 3600 ' gives a person's average speed in miles per hour if he or she travels one mile in The function s(x) = 60 + 04r 3600 (60+x) gives a person's average speed in miles per hour if he or she travels one mile in 3600(60 + x) x seconds more or less than 60 seconds. Use a linear approximation to s at 0 to find a person's approximate average speed if he or she travels one mile...
Professional baseball pitchers can deliver a pitch that can reach the blazing speed of 100 mph (miles per hour)
Professional baseball pitchers can deliver a pitch that can reach the blazing speed of 100 mph (miles per hour). A local team has drafted an up-and-coming left-handed pitcher who can consistently throw at 99.00 mph. Assuming the ball has a mass of 142.8 g and has this speed just before a batter would make contact, how much kinetic energy does the ball have? Kball = _______ From what height would the ball need to be dropped to attain the same energy, neglecting...

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...

show all calculations and do all parts of the question. Externalities II [Warning, this problem is an enhanced version of a negative externality problem. While I break it down into a series of short steps, it still may take a long time to figure out. Budget accordingly. Don’t skimp on your graph. Your picture will hopefully help you understand what is going on.] High levels of automobile traffic in big cities are incredibly costly to society. Time spent idling in...
