A 5.0 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown in the figure. The scale of the figure's vertical axis is set by Fs = 18.0 N. How much work is done by the force as the block moves from the origin to x = 8.0 m? Number Units

In the first figure, 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 end is fixed. The block is initially at rest at the position where the spring is unstretched (x = 0) when a constant horizontal force in the positive direction of the x axis is applied to it. A plot of the resulting kinetic energy of the block versus its position x is shown in the second figure. The scale of the figure's vertical axis is set by Ks = 8.0 J. (a) What is the magnitude of F→? (b) What is the value of k? (a)

In the arrangement of the first figure, we gradually pull the block from x = 0 to x = +3.0 cm, where it is stationary. The second figure gives the work that our force does on the block. The scale of the figure's vertical axis is set by W5 = 3.0 J. We then pull the block out to x = +7.0 cm and release it from rest. How much work does the spring do on the block when the block moves from xi = +7.0 cm to (a) x = +3.0 cm, (b) x = −1.0 cm, and (c) x = −7.0 cm? (a) (b) (c)
