A block is projected up a frictionless inclined plane with initial speed v0 = 5.05 m/s. The angle of incline is θ = 30.9°. (a) How far up the plane does it go? (b) How long does it take to get there? (c) What is its speed when it gets back to the bottom?
A box of mass 11[kg] is being pushed up a frictionless inclined plane by a force of 700[N]. The slope of the plane is 37 degrees. The box is pushed at 37 degrees – so the push is in exactly the same direction as the direction of the plane. Assume that the box was initially at rest. Suggestion: Draw a picture of this situation Draw a free body diagram for the box b. Draw a tilted free body diagram such...
