a 3.0 kg block has a speed of 5.0 m/s at the bottom of a ramp. The angle the ramp makes with the ground is 24 degrees. If the block reaches a height of 0.60 m, determine the force of friction acting on the block.

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?
