- A block is sent up an incline with a velocity of 3.51 m/s. Assume there is no friction between the incline and the block. The angle is at an incline of 31.1 degrees with the horizontal. A) How far up the incline does the block go? B) How long does it take to get there? C) What is it's speed when it gets back to the bottom?A 10 N of force is applied to a toy car and toy car accelerates to 2m/s^2. If 20 N of the force is applied on the same toy car, the toy car now accelerates to A. 2m/s^2 B. 3m/s^2 C. 4m/s^2 D. 6m/s^220. A box moves up a slope while being pushed in the direction shown. If there is friction between the box and slope, which of the following is correct? f Conserve Push Energy for box & Earth box moves up so AU= pos Wext = W A) The box gets faster as it moves up the slope. B) The box gets slower as it moves up the slope. C) None of the other choices must be correct. D) The box moves at constant speed. push Михо → push A² TAř| ces F co Push pos. E) The box gets faster but not by as much as if there was no friction. B Деви = fulonl = pos.
