It begins to accelerate ata constant rate (that 15, a constant angularacceleration) as it makes lts way halfwayaround the track. It then decelerates at thesame constant rate during the second halt ofthe lap. It completes the entire lap in a time of28.5 seconds. What is the car's top total (net)acceleration?A) 4.60 m/s^2B) 1.30 m/s^2C) 8.17 m/s^2D) 8.27 m/s^2

Car's top total acceleration is 8.27m/s2 Your option (d) is right.

Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 11.6 seconds to get up to its full speed of f1 = 78 revolutions per minute. Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 12 times while accelerating uniformly. t1 = 11.6 secondsn2 = 12 times a. Calculate the angular speed described in Case 1, given as f1 = 78 revolutions per minute, into units of radians/second. b. How many revolutions does the turntable make while accelerating in Case 1? c. Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/second2. d. Calculate the magnitude of the angular acceleration of the turntable (in radians/second2) while increasing to 120 RPM (Case 2). e. How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?
A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 35 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 22.6 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track?

An Aston Martin V8 Vantage sports car has a "lateral acceleration" of 5m/s². This is the maximum centripetal acceleration the car can sustain without skidding out of a curve path. If the car is traveling at a constant 45m/s on level ground, what is the radius R of the tightest unbanked curved it can negotiate?
