A 0.31-kg stone is held 1.2 m above the top edge of a water well and then dropped into it. The well has a depth of 5.6 m. (a) Taking y = 0 at the top edge of the well, what is the gravitational potential energy of the stoneEarth system before the stone is released? (b) ...
Two blocks are connected by a light string that passes over a frictionless pulley as in the figure below. The system is released from rest while m2 is on the floor and m1 is a distance h above the floor. (a) Assuming m1 > m2, find an expression for the speed of m1 just as i...
Im still confused. Ive tried solving for k a couple of different ways and the website tells me that I am wrong. My answers have ranged from .0286 to 791.1 N/m. Ive tried converting 1.55 cm to m, and it still says that I am wrong.
