In a cork gun, the spring force is a function of the strech orcompression of the spring. The spring is compressed by 5.5 cm andused to propel a 3.8g cork from the gun. a) What is the speed of the cork if it is released as thespring passes through its relaxed position? b) SUppose that the cork sticks to the spring and stretches it1.5cm before separation occurs. What now is the speed of the corkat the time of release? In a cork gun, the spring force is a function of the strech orcompression of the spring.

Explanation / Answer
If k is the spring consatnt then PE=KE 1/2*kx2=1/2*mv2 The speed is v=k/m*x x=0.055m m=0.0038kg Then x=5.5-1.5=4cm=0.04m Hence we get by it. The speed is v=k/m*x x=0.055m m=0.0038kg Then x=5.5-1.5=4cm=0.04m Hence we get by it.
