A student is pulling back the pouch of a slingshot to launch a small pebble.
The student pulls the pouch with a force of 90 N90\text{ N}90 N. This force acts on an area of 0.4 cm20.4\text{ cm}^20.4 cm2 on the student's fingers.
Calculate the pressure on the student's fingers.
pressure on fingers = .................... N/cm2\text{N/cm}^2N/cm2
The student's other hand holds the frame of the slingshot, resisting the same pulling force of 90 N90\text{ N}90 N. This force acts on a larger area of the hand than the force in (a).
State whether the pressure on this hand is greater than, the same as, or less than the pressure on the fingers holding the pouch.
State the type of energy stored in the slingshot's elastic band when it is stretched.
