Help! Force/Tension Problem
A 2.4 kg ball tied to a string fixed to the ceiling is pulled to one side by a force F to an angle of 32.1° from the ceiling.
(a) Just before the ball is released and allowed to swing back and forth, how large is the force F that is holding the ball in position?
(b) Just before the ball is released and allowed to swing back and forth, what is the tension in the string?
Hi all, I am new to physics, and this homework is kicking my butt! haha, so first I tried to convert the 2.4kg to Newtons (9.8N/kg), and then use sin and cos to find the force in the x and y directions. I get 19.9 in the x direction, and 12.5 in the y direction. Our homework is submitted electronically, though, and it doesn't think my answer for a) is right... I really don't know how to do b)
If someone could help me that would very much appreciated, this is due at 7 in the morning!
Thanks,
Damian
