A person is pulling a 50N block up a 60 degree incline over 0.8m determine the work done by the string on the block as the block is lifted 0.80m along the incline. The string tension is 50 N

How fast must the bucket move at the top of the circle so that the rope does not go slack?I did this where the sum of the centripetal forces is equal to the gravitational force and tension are... more

If an object is thrown upward with an initial velocity of 256 ​ft/second, then its height after t seconds is given by what equation?

Remember that average speed is total distance traveled divided by total time. The total distance is clearly 2 miles. So you need to figure out the total time.

I understand that people explain (in layman's terms at least) that the presence of mass "warps" space-time geometry, and this causes gravity. I have also of course heard the analogy of a blanket or... more

Today in class we were discussing the strong nuclear force, and our teacher was explaining about how the strong nuclear force counteracts the repulsion force between protons in a nucleus. When... more
