In the center in at the very right. I suppose if I change the axis of roation to the right side, the equation would be Torque=Ry(L)-300(L/2), but that gets me no where.
A sign with weight 800 N is hung from point B at the end of a uniform hoizontal rod of weight 300 N as diagrammed below. The rod is attached to the vertical wall by a hinge at point A. The supporting cable is attached to the rod at B and to the wall at C. The cable makes a 42 degree angle with...
Before I inundate you with various elementary problems I'm facing, I need help with the concept.
Fgrav=(GMm)/(r^2)
So Fgrav is in units of Newtons, correct? How would one convert that to m/s?
1. For an object in circular motion, which of the following is/are directed perpendicular to the plane of the circle?
Angular Acceleration, Tengintial Velocity, Angular Velocity, Tangential Acceleration, or Angular Displacement?
2. You are on Earth. Assume that one month is about 30 days...
I calculated that the average force exerted on the daughter is 160N, and that the magnitude of her velocity is 1.4 m/s. I know F=ma is a relevant formula to the question, but I'm stuck from that point on.
Well, while we're on the subject of helping.
If the coefficient of kinetic friction between the daughter's skates and the ice is mew = .1, how far will she slide before she is brought to a stop by the friction force?
If P = mv, then P^2/(2m) is:
I know the answer is Kinetic Energy, I just don't know the proof. Help?
A 70kg man and his 40kg daughter stand together on skates in the middle of a frozen lake. They push apart. Immediately after the push the father has an initial velocity of .8 m/s in on...
