a .225 kg ball tethered to a tall pole on a 1.37m rope is thrown so that it travels in a horizontal circle with the rope making an angle of 40 with the pole
a) what is the speed of the ball
b) what is the tension in the rope
i am stuck on this problem because i do not have a unit time to be able to use any of the equations dealing with circular motion
i started out with knowing that the radius will be the cos40*1.37m = 1.05 m
but after that I'm always left with two unknowns for any equation. any hints on what i could be missing...thanks!
