Two beetles run across flat sand, starting at the same point. beetle 1 runs 0.50 m due east, then 0.80 m at 30° north of due east. beetle 2 also makes two runs; the first is 1.6 m at 40° east of due north. what must be (a) the magnitude and (b) the direction of its second run if it is to end up at the new location of beetle 1?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
