Show all work (givens, unknowns, and equations used) in an organized fashion. BOX answers.
la) During a lawnmower race, a rider starts from rest and accelerates at I m/s/s for 10 seconds. The rider then
maintains a constant velocity for the remainder of the race, which takes an additional 20 seconds.
For the below questions, be sure to show all the work for the intermediate steps that allowed you to find the final
answers. CIRCLE the answers to these intermediate steps.
A) How far was the race?
B) What was the lawnmower's average velocity for the race?
lb) After the finish line in the above described lawnmower race, the lawnmower slows to a stop over a distance of
10 meters. What was the lawnmower's acceleration during this time?
I am still not sure how you got to the final result. I am still studying the work-energy theorem and on case 2 I don't understand how you simplified from the 1st formula line to the 2nd line. Can you please explain?
In the following scenarios, the velocity and acceleration vectors of a person are shown.a. Say whether the person is turning to their left or right, or not turning at all. Also say whether the person is speeding up, slowing down or moving at a constant speed. (Your answers for parts a) and b) can be the work shown for each other.)
b. How do you know whether the person is speeding up, slowing down or moving at constant speed? (Hint: Avoid the phrases “same direction,” which means parallel, and “opposite directions,” which means anti-parallel. Be sure that your answer encompasses B all possibilities, not just those two)
