A 0.25 kg ball is attached to a string. The ball goes around in a circle that is horizontal (parallel) to the ground. The circular path has a radius of 1.5 m. The rotation is at a constant rate of 50 rpm.
a) list the given
b) what is the tangential velocity of the ball?
c) what is the centripetal acceleration (magnitude and direction)?
d) what is the magnitude of the tangential acceleration?
e) what is the soure of the centripetal force?
f) what is the magnitude of this force?
g) what is the magnitude of this force?
h) what is the magnitude of this force if the radius of the balls path is doubled?
i) what is the magnitude of this force if the radius of the balls path is the original value but the speed doubles?
Homework Answers

A ball attached to a string of length 0.75 meters is whirled around in a circular path. It experiences a centripetal acceleration of 10 m/s^2. a. What is the tangential velocity of the ball? b. How long does the ball take to make one complete revolution?
A particle object undergoes uniform circular motion at a speed v around a circle of radius...
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...

A ball on the end of a string is whirled around in a horizontal circle of radius 0.340 m. The plane of the circle is 1.20 m above the ground. The string breaks and the ball lands 2.50 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. Magnitude m/s Direction

A child is twirling a 0.0120-kg plastic ball on a string in a horizontal circle whose radius is 0.100 m. The ball travels once around the circle in 0.500 s. (a) Determine the centripetal force acting on the ball. (b) If the speed is doubled, does the centripetal force double? If not, by what factor does the centripetal force increase? Question I need answered is, Why is gravity not considered when solving this problem?
