Web9 feb. 2024 · This is extremely important! The type of material and the quality of the snow affect the ride a lot. For example, metal goes faster than every other common material in use for sleds. Teflon (the polymer used in non-stick pans) is a runner-up, but is not really common! As for the snow, sledding on fresh, fluffy snow is not the best for a fast ride. Web19 okt. 2024 · The spring shown in the figure is compressed50 cmand used to launch a100 kgphysics student. The track is frictionless until it starts up the incline. The student’s coefficient of kinetic friction on the30?incline is0.15 How far up the incline does the student go? please i want final answer because i tried the correct formula but i couldnt … how does photosynthesis alter life on earth

WebThus, the greater the angle of incline, the greater the coefficient of static friction must be to prevent the cylinder from slipping. Check Your Understanding A hollow cylinder is on an incline at an angle of [latex] 60\text{°}. [/latex] The coefficient of static friction on the surface is [latex] {\mu }_{S}=0.6 [/latex]. WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. WebSquare by two, multiplied by 9.8 and multiplied by sine 30 degrees less. 0.14 multiplied by cost 30°. And from solving this we will get d. equals two 39.749 m. So this will be our required answer. Thanks for watching the video photo of upright piano
