Two cars start from rest from point A on a circular track of radius r=200 m. They travel in opposite directions with constant but different tangential accelerations and meet again at point B 10 seconds after they started moving. The angle traveled by the red car is Theta = 120 degrees. (Hint: you need to use radians in your equations)
a) Find the angular acceleration of the blue car in rad/sec^2.
b) Find the angular speed of the red car at point B.
c) Find the centripetal acceleration of the blue car at point B.
If a third charge, of 5, is now placed at the point = 3.00, = 4.00 find the components of the total force exerted on this charge by other two charges.
An automobile club plans to race a 700kg car at the local racetrack. The car needs to be able to travel around several 155m radius curves at 87km/h.
