Question

true or false? Heather and Matthew walk with an average velocity of .75 m/s eastward. If it takes them 25 min to walk to the park, their displacement must be 2.0 km to the east.

Answer 1

False. you have to find out how many seconds are in the 25 min. 60 x 25 is 1500sec. Then multiply 1500 by .75 to get 1,125m. There are 0.001 kilometers in a meter. Move the decimal point three spaces to convert m to km. 1,125m becomes 1.125km
