force
Question
A powerful slingshot has an elastic band that is pulled back until a maximum spring force of Fma x
is encountered (maximum force the person can exert). A projectile of mass M is released from
rest. Which of the following strategies could be applied to ensure the max projectile speed leaving the slingshot? Assume the same person is using the slingshot, i.e., same F
ma x
Replace the elastic band with a stiffer one (higher spring constant k).
Replace the elastic band with a softer one (lower spring constant k)
