Use the information below to anwser wuestion a-d
A ball is attached to a string and swung in a horizontal circle at a
constant speed. Assume air resistance is negligible.
a) Draw a free body diagram of the force(s) acting on the ball in the horizontal
plane. Also include in your diagram any non-zero velocity and/or Acceleration vector(s) of the ball label your coordinate system is the following
•positive us towards the centre of thecircle •negative is away from the centre of the circle
a) If the string tripled in length but the speed of the ball remained the same, show
mathematically how the inward force on the ball would change.
b)The ball is swung to revolve exactly 3 times in 1.0 s. What is the ball’s period?
c) The ball is swung to revolve exactly 3 times in 1.0 s on a 30.0 cm string. If the
string broke, what speed would the ball have when it is released?
