Solve complimentary function: Let y = emx then, d2y/dx2 - 5dy/dx + 4y = 0 m2emx - 5memx + 4emx = 0 (substituting fo...
The largest speed is obtained at the position of equilibrium.
v=Aw
So v= 2 x 1
v=2ms-1
dy/dx = 9x^2 + 2ax + b
x = 2, dy/dx = 9(2)^2 + 2a(2) + b = 36 + 4a + b
x = 1, dy/dx = 9(1)^2 + 2a(1) + b = 9 + 2a + b
