Consider the force table setup where a 200g mass is hung at 300º. To cancel this resultant force, two other forces are applied such that the components of the resultant force are individually canceled. What mass (in grams) must a be hung to cancel out the x-component of the resultant force? Consider the force table setup where a 200g mass is hung at 300º. To cancel this resultant force, two other forces are applied such that the components of the...

In this lab, we will balance forces by hanging masses from strings stretched across pulleys on a horizontal force table (an example force table is pictured below): a) If 50 g is suspended at 15 degree, and 75 g is suspended at 135 degree, what mass must be suspended at what angle to balance these two forces? b) If 45 g is suspended at 25 degree, 105 g is suspended at 85 degree, and 65 g is suspended at 330...

Vectors Equipment Force table 3 pulley clamps Masses and hangers Thread Procedure l. Assemble the force table by attaching the legs. The center post should be flush with the table top. 2. Take two threads (each about 60 cm long) and knot them together in the center, making four shorter threads. Pull one of the threads through the center post and tie it to one of the legs. This is the anchor string. 3. Attach mass hangers to the other...

Given Newton's law of universal gravitation where F is the force between two masses objects, m1 and m2 are the masses of the two bodies and r is the distance between the two bodies. Determine the units of G in two ways 1) including Newtons, N, as one of the units and 2) not including N. (hint...if you don't recall what the dimensions of N are, think of Newton's second law!
