Frictional force acting:FMax= uR = 0.7 x 5 x 9.81 x cos(30) FMax = 29.7NWeight acting down the slope:F = 5 x 9.81 x sin(30)F = 24.5NFric...
This question is split up into two parts.Firstly recall the trigonometric identities you know, the trick here is to eliminate one of the squared terms. Using 4sin^2(x) +4cos^2(x) = 4, the cos term i...
First cancel down the fractions to make the numbers as small as possible, then make all fractions have the same denominator. 12/30 becomes 2/5. 14/20 becomes 7/10. So the new fractions are 4/5 3/8 2/5 and...
The rule for differentiating a simple equation such as this is, to times the coefficient by the power and the take one away from the power. Therefore, lets look at 5x^4 you would times the 5 by 4 to get 2...
