Approaching one of the many sharp horizontal turns in the Monaco Grand Prix, an experienced Formula-1 driver slows down from 150 km/h to 47.0 km/h while rounding the bend in 11.0 s. If the driver continues to decelerate at this same rate and the radius of the curve is 15.0 m, what is the acceleration of the car the moment that its speed reaches 47.0 km/h? (Enter the magnitude.) m/s2

In April 1974, Steve Prefontaine completed a 10 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 7.71 km mark at a time of 25.0 min. If he accelerated for 60 s and then maintained his increased speed for the remainder of the race, มั่ " calculate his acceleration over the 60 s interval. Assume his instantaneous speed at the 7.71 km mark was the same as his overall average speed up to that...

The acceleration of a race car for the first few seconds of the race can be approximated by the a(t) = A + Bt linear formula, where t is the time measured in seconds and the values of the constants A and B are: A = 16.0 m/s2 and B = -2.00 m/s3. What is the speed of the car 2.30 s after it starts from rest? How much distance does the car cover during this 2.30 s time period?

A tortoise and hare start from rest and have a race. As the race begins, both accelerate forward. The hare accelerates uniformly at a rate of 1.4 m/s2 for 4 seconds. It then continues at a constant speed for 11.4 seconds, before getting tired and slowing down with constant acceleration coming to rest 84 meters from where it started. The tortoise accelerates uniformly for the entire distance, finally catching the hare just as the hare comes to a stop. 4)...
