Q)14
Given , x = 2t^2 + 5
dx/dt = v ; dx^2 / dt^ 2 = a
v = 4t ; a =4
So , Force on 3 kg particle = ma = 3* 4 = 12
W = f.S
So , distance covered in 3 seconds = Position of x during 3rd second - position of x at t =0
Or S = X(3) - X(0) = (2*(3^2) - 2*(0)) = 18
W = 12 * 18 = 216 J
Q)16 U = x^2 - 5x
At equilibrium , dU / dX = 0
So,2X -5 = 0
X = 5/2 =2.5
Hope this helps ,
