A force of 25.0 N is needed to move widgets up a smooth incline 10.0 m long in a widget factory. The widgets weigh 125N each. a.) Assume the incline is 100 % efficient.

How high above the floor is the top of the incline?

c.) Now assume that the incline is 75 % efficient, which is probably more likely. How high above the floor is the top of the inline?

Find the dimensions and area of the largest rectangle that can be inscribed in the upper half of the ellipse. (give your answers in terms of a and b. enter the dimensions as a comma-separated list.)

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

Diego kicks a soccer ball from the end line. his fellow students time and mark the soccer ball as it moves down the field. the graph represents the ball's progress. based on the graph, during what time is the velocity constant and positive?
