The weight of the ball, TA, and TB vectors make a right angle triangle such that:
TB is the hypotenuse.
TA is the opposite
Weight is adjacent.
cos θ = mg/TB
A large wrecking ball is held in place by two light steel cables.
If the mass m of the wrecking ball is 4040 kg, what is the tension TB in the cable that makes an angle of 40.0 with the vertical?
Take the free fall acceleration to be g = 9.80 m/s.
If the mass m of the wrecking ball is 4040 kg, what is the tension TA in the horizontal cable?
Take the free fall acceleration to be g = 9.80 m/s2.
