Question

hello,

i need help with question 8 of this question.

 

Hanging Masses 8. m. = 3.3 kg hangs from a spring in a motionless elevator. The spring is extended x = 13 cm from its A single mass m1 unstretched length. 1) What is the spring constant of the spring? 248.76 N/m Submit 2) m m2

4) Now the elevator is moving downward with a velocity of v = -2 m/s but accelerating upward with an acceleration of a = 4.5 m/s?. (Note: an upward acceleration when the elevator is moving down means the elevator is slowing down.) What is the force the bottom spring exerts on the bottom mass? 94.38 Submit 5) What is the distance the upper spring is extended from its unstretched length? 114 cm Submit 6) Finally, the elevator is moving downward with a velocity of v = -3.8 m/s and also accelerating downward at an acceleration of a = -2.2 m/s?. The elevator is: speeding up slowing down moving at a constant speed Submit 7) Rank the distances the springs are extended from their unstretched lengths: X1 = X2 = X3 X1 > X2 > X3 ×1 < x2 < X3 Submit 8) What is the distance the MIDDLE spring is extended from its unstretched length? 161.865 cm Submit (Survey Question) 9) Below is some space to write notes on this problem
