A object of mass 3.00 kg is subject to a force Fx that varies with position as in the figure below.

Find the work done by the force on the object as it moves as follows:
(a) from x = 0 to x = 4.00 m
1
Your response differs from the correct answer by 10% to 100%. J

(b) from x = 5.00 m to x = 7.00 m
2 J

(c) from x = 14.0 m to x = 15.0 m.
3 J

(d) If the object has a speed of 0.500 m/s at x = 0, find its speed at x = 5.00 m and its speed at x = 15.0 m. speed at x = 5.00 m 4 m/s
speed at x = 15.0 m 5 m/s
