Question

Prin Deadline: 100% until Saturday, September 1 at 8:00 AM Standard Vertica Mass On Two Springs Mass On A block with mass m 6.6 kg is attached to two springs with spring constants Kieft 34 N/m and kright 54 N/m. The block is pulled a distance x - 0.26 m to the left of its equilibrium position and released from rest. 1) What is the magnitude of the net force on the block (the moment it is released)? 22 88 N Submit Your submissions: 22.88 Computed value: 22.88 Feedback: Correct! Submitted: Monday, September 3 at 5:06 PM 2) What is the effective spring constant of the two springs?

Explanation / Answer

block mass, m = 6.6 kg

spring constant, kleft = 34 N/m ; kright = 54 N/m

displacement of block, x = 0.26 m

1. Net force on the block , F = (kleft + kright). x = ( 34 + 54 ) x 0.26 = 88 x 0.26 = 22.88 N

2. Effective spring constant , keff = kleft + kright = 34 + 54 = 88 N/m
