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

c. experiencing functional fixedness.

Explanation:

We refer to functional fixedness when the person can only see one function for each object and cannot use it for more than one task.

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

A., d., and f i think

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
