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 below. (a) How much work is done by the force as the block moves from the origin to x = 8.0 m? (b) It the block has a speed of 2.1 m/s at the origin, what is its speed when it reaches x = 8.0 m?

A object of mass 3.00 kg is subject to a force Fx that varies with position as in the figure below. (a) Find the work done by the force on the object as it moves from x = 0 to x = 4.00 m. J (b) Find the work done by the force on the object as it moves from x = 4.00 m to x = 10.0 m. J (c) Find the work done by the force on the object as it moves from x = 10.0 m to x = 18.0 m. J (d) If the object has a speed of 0.550 m/s at x = 0, find its speed at x = 4.00 m and its speed at x = 18.0 m. speed at x = 4.00 m m/s speed at x = 18.0 m m/s

Problem Statement: Dianne the Duck is moving along a straight line in a river. The net force on Dianne is shown on the graph below. (a) What is the total work done on Dianne as she moves from x = 0 m to x = 10 m? (b) If Dianne's mass is 1.25 kg, and she initially started her 10 m trip with a speed of 2.828 m/s (i. e. when she passed x = 0), what is her speed when she reaches x = 10 m?
