A block slides down a ramp, which is on a table, as shown. The ramp makes an angle θ with the horizontal. It takes it t1 seconds to slide down the ramp of length L, starting from rest. What is the speed of the block at t1? L t1 2 Lt1 sin(θ) 2L t1 cos(θ) 2L t1 gsin(θ) t1 not enough information
![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)
