Question
A 0.150-kg frame, when suspended from a coil spring, stretches the spring 0.051 m. A 0.200-kg lump of putty is dropped from rest onto the frame from a height of 30.0 cm. Find the maximum distance the frame moves downward from its initial position. ____ m A 0.150-kg frame, when suspended from a coil spring, stretches the spring 0.051 m. A 0.200-kg lump of putty is dropped from rest onto the frame from a height of 30.0 cm. Find the maximum distance the frame moves downward from its initial position. ____ m ____ mExplanation / Answer
for spring:
force F = mg = Kx
spring constant k = mg/x
k = 0.150 * 9.8 /( 0.051)
k = 28.82 N/m
from consevrvation of eenrgy
KE = PE
0.5 kx^2 = mg(0.3 + x)
0.5* 28.82 * x^2 = 0.2 * 9.8 * (0.3 + x)
x = 0.281 m
