A plumb-bob hangs from the roof of a railroad car. The car travels around a circular track of radius 228 m at a speed of 63 km/h. At what angle from the vertical does the plumb bob hang while the car travels around the circular track?
What is the angular acceleration of the turbine?
What is the centripetal acceleration of the tip of the blades at ?
The driver of a car moving at 90.0 km/h presses down on the brake as the car enters a circular curve of radius 150.0 m. If the speed of the car is decreasing at a rate of 9.0 km/h each second, what is the magnitude of the acceleration of the car at the instant its speed is 60.0 km/h?
