A 1.5 kg mass is attached to a vertically oriented spring, stretching it 0.45 m. The mass is moved upwards 0.25 m from its equilibrium position and held. A 0.8 kg mass is added to the hanging mass and the total mass is released from rest. The frequency of oscillation is most nearly: 1.02 Hz 1.67 Hz O 1.47 Hz O 1.15 Hz 0.74 Hz 0.83 Hz O 0.96 Hz 0.60 Hz Clear selection

An elephant has legs that stretch 2.30 m from its shoulders to the ground. How much time is required for one leg to swing forward after completing a stride? What would you predict for this elephant's stride frequency? That is, how many steps per minute will the elephant take?

A mass mm at the end of a spring oscillates with a frequency of 0.86 HzHz . When an additional 780 gg mass is added to mm, the frequency is 0.63 HzHz .What is the value of m?
