Question

A 1.60 kg object is held 1.40 m above a relaxed, massless vertical spring with a force constant of 340 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? ____________m???? (b) Repeat part (a), but now assume that a constant air-resistance force of 0.750 N acts on the object during its motion. ___________m???? (c) How far does the object compress the spring if the same experiment is performed on the moon, where g = 1.63 m/s^2 and air resistance is neglected? __________m ????

Explanation / Answer

velocity of obj when it hits the spring = srt( 2gh) = 5.23 m/s mgh = 1/2 Kx^2 = x=0.359 m. if a constant force was there, mgh - 0.750h = 0.5 Kx^2 x= 0.3506 m. if g= 1.63, on moon, x= 0.146 m.
