Hikers came across a deep narrow well and decided to find its depth. They dropped a pebble into the well and heard the sound of the pebble hitting the bottom of the well in 7s. Using this information they found the depth of the well. How deep is the well? Assume that the velocity of sound is...

A mass m is 5kg and another mass, M=6kg. Find the acceleration of this system if the kinetic friction is 0.1 and theta = 30 degrees. Find all tensions of connecting ropes. For which values of M will the system stay in an equilibrium position?Assume that the static friction coefficient is 0.15...

A car moves from point A to point B along a straight line. The car passes the first third of the distance with a constant velocity v1. The second third of the distance the car travels with a constant velocity v2 and for the last third of the distance the car moves with a velocity v3. What is the...

too much information, how do?

I'm not sure how to graph this properly.

I don't get it, sned answrs

In kind of a predicament where my teacher is horrible, he rambles on too much and cannot explain separation techniques (first topic) properly, kind of just names it and dosen't explain the process. I'm unsure.
