Physics is the bane of my existence
 

Hey guys I can't figure out this problem for the life of me....

A 3.50 kg object is attached to a vertical rod by two strings as in the figure below. The object rotates in a horizontal circle at constant speed 4.95 m/s.

What is the tension on the lower and upper string D:?

You come to us when you have a school problem.. hmph!

O.o would you like to me to come to you other times too o.O? I quietly help out around here .-. /gives lots of money when asked for FF events D;

Aw ok I'm sorry.. I'll take that back.. kekeke

lol....no one in my class can get it either D; i think this problem is cursed

Do you have a formula for tension? That's the formula for force right?

I wonder if Lam knows. Kekeke. He just posted a super long thing on Physics. If I see him online, I'll have him look at this.


/has never taken a Physics class in my life

F=MA...tension is essentially force.

It should be like this I think

cos θ = 1.5/ 2
= 41.41 degrees
T1y = mg
T1 sin θ = mg
T1 sin 41.41 = 3.5(9.8)
T1 = 51.85N

but it doesn't work D;

T1 = 49.28 N?

Bleh.

Try centripetal motion equation.
