A drone carries a sensor on a 2.5 m cable and flies in a horizontal circular path. The sensor completes 45 revolutions in 60 seconds. (a) Calculate the period of the sensor's motion. (b) Calculate the speed of the sensor. (c) Hence, calculate the centripetal acceleration of the sensor.
A drone follows a circular path of radius \(42\) m at a constant speed of \(15\) m s\(^{-1}\). Calculate the magnitude of the centripetal acceleration experienced by the drone.
A ball is attached to a string and rotates in a horizontal circle of radius 0.45 m. The ball completes one full revolution in 0.80 s. Calculate the centripetal acceleration of the ball. Show your working.
A racing car travels around a circular track of radius 85 m. The car completes one lap in 12.5 s. Calculate the magnitude of the centripetal acceleration of the car. Show your working.
