Awesome. Thanks. I will just have to be more careful when I set up the force diagrams I guess. After following the directions you gave I got the right answer no problem.

Homework Statement A uniform diving board, of length 5.0 m and mass 53 kg, is supported at two points; one support is located 3.4 m from the end of the board and the second is at 4.6 m from the end (see the figure below). What are the forces acting on the board due to the two supports when a...

Sorry but that still isn't helping me. Are you just using the F=ma formula?

Homework Statement (a) Find the altitude above the Earth's surface where Earth's gravitational field strength would be two-thirds of its value at the surface. Assume re = 6.371 multiplied by 10^3 km. wrong check mark km (b) Find the altitude above the Earth's surface where Earth's gravitational...

Thank you! Finally got it.

Thanks for the welcome. And yes I had that, I just input the equation wrong into the computer. When I go through and try an answer I have gotten 2.06 for the time it takes for it to stop rising which I would think i could just input into the formula to have it be some thing like...

Homework Statement A stone is launched straight up by a slingshot. Its initial speed is 20.2 m/s and the stone is 1.40 m above the ground when launched. Assume g = 9.80 m/s2. A: How high above the ground does the stone rise? B: How much time elapses before the stone hits the ground? Homework...
