Homework Statement
Is it possible to solve for the magnitude of tension without using the mass of the object? : You use a string to suspend a cork ball with a mass of 22g from the ceiling of a moving speedboat. The ball and the string hang at an angle of 32.5degrees from the vertical. The acceleration of the speedboat is 6.2m/s^2. Determine the magnitude of tension in the string. Do you need to know the mass of the ball to make this calculation? Why or why not?
Homework Equations
Fnet=ma, (Fnet)x=ma=(Ft)x
The Attempt at a Solution
I solved this using the mass, but could not solve without using the mass. To solve, I just did
Fnetx=ma
ma=Ftx
ma=Ftsin32.5
I just subbed in m and a after that and solved for Ft. I got the right answer, which is 0.26N.
I wrote that you need the mass in order to solve for FT in this case.
Is this right?
