1)A spring with k = 40.0 N/m is at the base of a frictionless 30.0° inclined plane. A 0.50 kg object is pressed against the spring, compressing it 0.2 m from its equilibrium position. The object is then released. If the object is not attached to the spring, how far up the incline does it travel...
1) A wheel is rotating at a rate of 2.7 revolutions every 3.0 s. Through what angle, in radians, does the wheel rotate in 1.0 s?
I tried to solve this problem by:
{a} 360 x 2.7 = 972
{b} 972 / 3 = 324
{c} 364 / (180 / Pi) = 5.65
Yet, 5.65 is not the answer. The rust coated around...
Again, I follow your logic perfectly, but another difficulty has cropped up. How on Earth do I isolate T2 in this monster?
((T2)cos60/cos30)sin30+(T2)sin60 = 198
I have made several attempts at this already, and all were failures- forcing me to realize that I need to brush up on some...
Okay, I follow your logic thus far, and it makes perfect sense. My only problem is that I am not sure how to solve those equations without at least one value plugged in for T1 or T2. Again, I'm sure it's something right beneath my nose that I'm neglecting here. :smile:
Okay, I tried your method to the best of my ability, and the answer I got was 457.3N for the right string. Is that the correct answer? And if not, could you perhaps explain the process better to me so that I can retry it? Thank you for replying.
A 198N bird feeder is supported by three cables. Find the tension in each cable.
For the angles, see this picture: http://www.webassign.net/sf5/p4_13.gif
{a} Yet again, I split the larger triangle in two by using a positive 198N force, making the large triangle's lower 90 degree angle into a...
There are two wires connected to a ceiling with a light fixture hanging at their ends. The light fixture exerts a force of 80N, while the wires make a 40 degree angle with the ceiling. What is the tension in the two strings? The diagram roughly looks like this:
