- A car sits at rest at the starting line of a circular racetrack. It begins to accelerate at a constant rate (that 15, a constant angular acceleration) as it makes Its way halfway around the track. It then decelerates at the same constant rate during the second halt of the lap. It completes the entire lap in a time of 28.5 seconds. Also, the radius of the racetrack is 42.0 m. What is the car's top speed?A) 25.6 m/SB) 44.1 m/SC) 18.5 m/sD) 35.1 m/sHow fast (in rpm) must a centrifuge rotate if a particle 7.5 cm from the axis of rotation is to experience an acceleration of 2.0×105 g's? Express your answer using two significant figures.The bus's wheels have a radius 26 cm. The bus starts at rest and accelerates at a constant speed until it reaches an angular speed of 10.4 rev/s. During this period, the bus moved 100 m. How many revolutions does the wheel go through?
