Get started for freeProblems 50 show a partial motion diagram. For each:
a. Complete the motion diagram by adding acceleration vectors.
b. Write a physics problem for which this is the correct motion
diagram. Be imaginative! Don’t forget to include enough
information to make the problem complete and to state clearly
what is to be found.
c. Draw a pictorial representation for your problem.
For Problem 40, draw a complete pictorial representation. Do not solve these problems or do any mathematics.
A motorist is traveling at 20 m/s. He is 60 m from a stoplight when he sees it turn yellow. His reaction time, before stepping on the brake, is 0.50 s. What steady deceleration while braking will bring him to a stop right at the light?
A softball player slides into second base. Use the particle model to draw a motion diagram showing his position and his average velocity vectors from the time he begins to slide until he reaches the base
