Individuals who have difficulty using a tool for anything other than its proper use may have difficulty solving a problem due to a. experiencing mental set b. imposing unnecessary constraints c. experiencing functional fixedness d. focusing on irrelevant information

An example would be not being able to use a container as a shelf or a hammer as a paperweight instead of just hammering.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
