Cars A and B are traveling around the circular race track. At the instant shown. A has a speed of 90 ft/s and is increasing its speed at the rate of 15 ft / whereas B has a speed of 102 ft/s and is decreasing its speed at 25 ft/? (Figure 1) Determine the relative acceleration of car A with respect to car B at this instant Express your answer to three significant figures and include the appropriate units.
In an elastic collision two cars are traveling toward one another and crash head-on. The first car (A) has a mass of 700 kg and is traveling 20 m/s East and the second car (B) has a mass of 800 kg and is traveling 5 m/s West. After they collide, the first car (A) bounces backward at a rate of 15 m/s, what is the velocity of car (B) traveling at? A.0.625 m/s West B. 25.6 m/s East C. 25.6...

1) A car with mass m = 1000 kg is traveling around a circular curve of radius r = 990 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.66 when dry and μw = 0.26 when wet. a) Write an expression for the maximum magnitude of the force of static friction Ff acting on the car if μs is the coefficient of friction. b) What is the maximum tangential...
