1. Sketch a position-time graph that corresponds to the description below: The object starts at a position of negative four meters • It moves at a velocity of +0.5 m/s for six seconds • The object is then at rest for three seconds • It reverses direction and moves at a speed of 0.75 m/s for four seconds • It continues at a constant speed for another two seconds so that its average velocity over the entire trip is +1/3 m/s.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
