(1) A 1200 kg racecar goes at a constant speed of 120 km/h round a curved section of track that has a radius of 60 m. (i). What is the speed of the car in m/s? (ii). What is the car's centripetal acceleration in m/s² and in g's? (iii). What is the centripetal force acting on the car? In the figure below, the net external force on the 22 kg mower is stated to be 58 N. (2). If the force of friction opposing the motion is 12 N, (a). (b). Fret what force F (in N) is the person exerting on the mower? (Enter the magnitude.) Suppose the mower is moving at 1.5 m/s when the force F is removed. How far (in m) will the mower go before stopping? Ans: 2.06 m (1) A 1200 kg racecar goes at a constant speed of 120 km/h round a curved section of track that has a radius of 60 m. (i).
