Joaquin mows the lawn at his grandmother’s home during the summer months. joaquin measured the distance across his grandmother’s lawn as 11.5  meters. a. if joaquin mows one length across the lawn from east to west in 7.10  seconds, then what is the velocity of the lawnmower? b. once he reaches the edge of the lawn, joaquin turns the lawnmower around. he mows in the opposite direction but maintains the same speed. what is the velocity of the lawnmower? show your work!

Velocity is define as how fast an object is moving, and in what direction, it is a vector quantity, meaning velocity has both magnitude and direction. Anything goes to the left is negative, and anything goes to the right is positive.

a. Direction from east to west, given distance 11.5 meters, and time of 7.10 s

V = displacement/time  V = -11.5/7.10 S  V = -1.62 m/s  (going left)

b. Joaquin reaches his original position. Displacement is now zero.

    Velocity of the lawnmower is equal to "zero" but if we calculate for the average speed of the lawn, you just have to add the distance covered and the time it take to go back at the original position or point of origin

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.
