A car is traveling around a circular track of 240 - m radius . If the magnitude of its total acceleration is 3 m / s2 at the instant when its speed is 75 km / h , determine the rate at which the car is changing its speed

1. During a braking test, a car is brought to rest beginning from an initial speed of 60 mi/h in a distance of 120 ft. With the same constant deceleration, what would be the stopping distance "s" from an initial speed of 80 mi/h? Ans. 213 ft

You are driving down a straight road at night in your McLaren MCL34 Formula 1 racecar at an entirely illegal speed of 98 m/s when Bambi and Thumper jump onto the road in front of you. Because you were texting while driving (also illegal), your reaction time is a rather slow; 1.3 seconds before your foot touches the brake. How far did you travel during this time? O a. 98 m O b. 127 m O c. 101 m O d. 134 m O e. 112 m Clear my choice

1. You are driving at 8.00 m/s south. You accelerate uniformly at 1.10 m/s? north for 5.00 seconds. How fast are you going at the end of the 5.00 seconds? What is your displacement?
