A block weighing 6 kg is on a plane with an incline of (5pi . . . - Socratic 0 8N up the slope Start by setting your problem up in a diagram like so: (g is the acceleration due to gravity, value =9 81ms^-2) Then think about which formulae and physics concepts you will need to solve the problem We have the idea of equilibrium We want the forces to balance so that the block doesn't move So any resultant force should be zero We are mostly concerned with the forces
Question #7be2f - Socratic Explanation: The slope, #m#, of the line segment between the points # (-1,-2)# and # (-5,8)# is: #m = (8- (-2)) (-5- (-1))# #m = -5 2# The slope, #n#, of any line
Question #8cb98 - Socratic int xsqrt (x+1)*dx=2 5 (x+1)^ (5 2)-2 3 (x+1)^ (3 2)+C a) For trigonometric substitution method, I used x= (tanu)^2 and dx=2 (secu)^2*tanu*du Hence, int 2 (secu)^3* (tanu)^3*du =2int (secu)^2* (tanu)^2*secu*tanu*du =2int (secu)^2* [ (secu)^2-1]*secu*tanu*du After using y=secu and dy=secu*tanu*du transformations, this integral became int 2y^2* (y^2-1)*dy =int (2y^4-2y^2)*dy =2 5y^5-2 3y^3+C =2
