A man and his bike are 95 kg. His instantaneous speed at one point is 14m/s. The next time his speed is checked he is going 28m/s. If the second speed was taken 7 seconds later, what force must the man have given his bike to change the speed? What was the bicyclist’s final momentum?

i think 5 miles per hour

step-by-step explanation:

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
