The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.75 kg, and the spring has a spring constant of 57 N/m. The coefficient of static friction between the box and the table on which it rests is -0.79. How far can the spring be stretched from its unstrained position without the box moving when it is released? 18 35 38 43 57 the tolerance is +/-2% LINK TO TEXT dy Question Attempts: O of 6 used SAVE FOR LATER SUBMIT ANSWERExplanation / Answer
mus * Fn = k x
mus * m g = k x
x = mus * m * g / k
= (0.79 * 0.75 * 9.8) /(57)
spring can be stretched x = 0.102 m
