2. A car is driving at constant angular speed along a 20 m radius circular track. The car completes one revolution of the track in 10 seconds. Calculate: (i) The (tangent) speed of the car. 12.6 m/s (ii) The angular speed of the car. 0.63 1/s or 0.63 rad/s (iii) The centripetal acceleration of the car. 7.9 m/s2 (iv) The RPM (i.e. revolutions per minute) of the car. 6 RPM THE ANSWERS ARE IN BOLD, COULD YOU PLEASE SHOW THE...
A 88 kg sprinter runs around a circular track with a radius of 28 m at a velocity of 13 m/s. What type of force causes the runner to turn and what is it's magnitude? Type of Force = Force = Newtons
A electric model train travels at 34.7 cm/s around a circular track of radius 1.67 m. How many revolutions does it perform per second, i.e, what is the motion\'s frequency? Find the train\'s period of revolution.
1) A cyclist rides around a circle track with a constant speed of 8 m/s. If the radius of the track is 150 m then what acceleration does it experience? 2) A 75 kg tightrope walker is in the middle of the rope. The tightrope sags in the middle and creates a 30 degree angle below the horizontal. What is the tension in the cable? 3) A 0.75 kg yo-yo is spun around at a constant speed in a circle....
