A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...
When an object moves in uniform circular motion, the direction of its acceleration is is directed toward the center of its circular path. depends on the speed of the object. in the opposite direction of its velocity vector. is directed away from the center of its circular path. in the same direction as its velocity vector
(b) For an object in uniform circular motion, derive the expression which relates centripetal force to speed. (5 marks] (c) A person swings an object around in a circle on the end of a steel wire, at a constant speed completing one revolution every 1.9 s. The object has a mass of 1.75 kg. The radius of the circle is 2.3 m. (i) Draw a diagram indicating the direction of the following vectors: velocity, centripetal acceleration, centripetal force. [3 marks]...

(a) What is the magnitude of its net linear acceleration 19.0 s later? (b) What angle does this net acceleration vector make with the car's velocity at this time? Question 6 A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550...
Consider an object in uniform circular motion. A.) If the trajectory and the mass of the object are unchanged, but the centripetal force is doubled, is the object's speed multiplied by a factor of 1, square root of 2, 2, or 4? B.) If the mass of the object is halved and the radius of the circle quadrupled, while keeping the mass of the object the same, is the object's speed multiplied by a factor of1, square root of 2,...
