A block slides down a straight ramp inclined at an angle of θ = 30∘, then slides horizontally off the end of a table as shown. There is no friction, and the block's speed leaving the table is the same as its speed at the end of the ramp. At what distance x from the bottom of the ramp should you release the block so that it lands in the bucket? 15 cm 49 cm 60 cm 30 cm 21 cm
![A box (mass m ) is released from rest and slides down an inclined rough surface. The friction interaction results in an increase in thermal energy of the two surfaces (box and incline) of Efric ( > 0). The incline of height H makes an angle θ with respect to the horizontal. This problem should be solved using energy methods, not F→net = ma→. A. [6 pts] Find a symbolic expression for the speed of the block when it gets to the bottom of the incline, vbot. Your answer should be in terms of the given quantities m, H, θ, Efric and constants. Some symbols may not be needed. B. [2 pts] D. Does your result make sense if the height of the incline is larger/smaller? "Yes" or "No" is not sufficient. Explain the behavior you expect and whether your result shows that. C. [2 pts] Does your result make sense if there is no friction? "Yes" or "No" is not sufficient. Explain the behavior you expect and whether your result shows that.](https://www.doubtrix.com/uploads/editor/5975287451TYFbwLLQbH.jpg)
