The coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.74. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 210-kg motorcycle experiences while skidding to a stop. The mass includes the rider.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

your answer is option c.
