Question 1

The oscillation of the 2.0-kg mass on a spring is described by where x is in centimeters and t is in seconds. What is the force constant of the spring?

◦
4.0 N/m

◦
0.80 N/m

◦
16 N/m

◦
32 N/m

◦
2.0 N/m


Question 2

Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles θ1, θ2 and θ3 respectively and released. The approximation sin θ = θ holds for all three angles, with θ3>θ2>θ1. How do the angular frequencies of the three pendulums compare?

◦
ω3>ω2>ω1

◦
