.
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N/m

(b) What maximum force is required to load the gun?
.
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully

Explanation / Answer

Spring PE = KE of projectiles 1/2 kx^2 = 1/2 mv^2 k *( 0.088)^2 = 0.0032 * (40.1)^2 k= 664.47N/m F= kx = 664.47 * (0.088) = 58.47336 N
