Four 100-g masses are hung from four springs, each with an unstretched length of 10 cm. The four springs stretch as noted in the following diagram: Now, each of the masses is lifted a small distance, released, and allowed to oscillate. Which mass oscillates with the highest frequency? [Useful formula: k = F x and  f = 1 T = 1 2 π k m ]Pendula.jpg 

The velocity of a certain simple harmonic oscillator is given by v(t) = -(12.0 m/s)sin[(6.0 rad/s)t]. What is the amplitude of the simple harmonic motion?

A 2.2-kg object is suspended from a spring with k = 18 N/m. The mass is pulled 0.35 m downward from its equilibrium position and allowed to oscillate. What is the maximum kinetic energy of the object?

A BMI over 25 is always an indicator of poor health.

All fats are harmful to the body and should be avoided in a healthy diet.

Which training method involves performing exercises against resistance to build strength?

What is one benefit of maintaining a healthy body composition?
