Document Summary
Constant acceleration equations: x(t) = x0 + v0t + at2/2 v(t) = v0 + at. Velocity and acceleration v = x/ t a = v/ t. Freely falling motion: g = 9. 8 m/s2 ay = -g y(t) = y0 + v0yt - gt2/2. Components: vx = vcos vy = vsin . = i v = r, a = r. L = r x p k = 1/2 i 2. Center of mass: xcm= mr / m. U(r) = -gmm/r: an astronaut inside a spacecraft is orbiting a black hole at a distance of. The black hole has mass of 1x1031 kg. The rod turns without friction in the bracket and the moment of inertia of thepaper and the rod about the axis is 0. 26 kg m2. The other end of the bracket is attached by a frictionless hing to the wall such that the bracket makes an angle of 30 degrees to the wall.
