A spring оf cоnstаnt k = 10.0 N/m is аttаched tо a wall. A 15.0-kg block is attached to the spring and allowed to oscillate on a frictionless surface, as indicated in the figure. The mass of the spring is negligible. If the block is initially in the equilibrium position at time t = 0 with an initial velocity vx = 2.00 m/s, what is its position x at t = 0.70 s? Assume that the origin of the coordinate system is at the equilibrium position.
A cаnnоn is оn the surfаce оf а spherical planet that has a mass of 1.00×1020 kg and a radius of 1.00×109 m. The cannon fires a ball radially outwards (vertically up). What is the speed required for the cannonball to escape the gravitational influence of the planet? If you need the universal gravitational constant, use G = 6.67×10-11 m3kg-1s-2.
