Below are sample questions representative of the exercises included on this worksheet and related 12.53 Kinetic Energy and the Work Energy Theorem skill assessments:

Problem 1Difficulty: Mastery

A 2.0 kg particle moves from x = 0 to x = 0.40 m under a net force F = -50x, with x in meters and F in newtons. It starts at 5.0 m/s. What is its speed at x = 0.40 m?

A4.2 m/s

B5.4 m/s

C3.0 m/s

D4.6 m/s

Solution & Explanation:The work is the integral of -50x dx from 0 to 0.40: -25(0.40²) = -4.0 J. K_i = 1/2(2.0)(5.0²) = 25 J, so K_f = 21 J and v_f = sqrt(2(21)/2.0) = sqrt(21), about 4.6 m/s.

Problem 2Difficulty: Mastery

A particle's kinetic energy as a function of position is K(x) = 12 + 18x - 2x² joules. What is the net work from x = 1.0 m to x = 5.0 m?

A+52 J

B+28 J

C+24 J

D-24 J

Solution & Explanation:By the work-energy theorem, work from x = 1 to x = 5 is K(5) - K(1). K(5) = 52 J and K(1) = 28 J, so W_net = +24 J.

Problem 3Difficulty: Mastery

A 0.50 kg glider initially moves at 12 m/s. A fan does +20 J of work while drag does -38 J. What is the glider's final speed?

A6.0 m/s

B8.5 m/s

C9.8 m/s

D13.0 m/s

Solution & Explanation:The net work is +20 J - 38 J = -18 J. K_i = 1/2(0.50)(12²) = 36 J, so K_f = 18 J. Then v_f = sqrt(2(18)/0.50) = sqrt(72), about 8.5 m/s.
