• 30 In Fig. 7-10a, a block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (spring constant k) whose other "O 0.5 1 1.5 2 end is fixed. The block is initially at x (m) rest at the position where the spring Figure 7-36 Problem 30. is unstretched (x = 0) when a con- I stant horizontal force É in the positive direction of the x axis is applied...
A 3.1 kg block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction of an x axis is applied to the block. The force is given by F(x) = (6.8-x^2) i N, where x is in meters and the initial position of the block is x = 0. (a) What is the kinetic energy of the block as it passes through x = 3.9 m? (b) What is the maximum kinetic energy...
