The force F on an object is the product of the mass m and the acceleration a. In this problem, assume that the mass and acceleration both depend on time t, hence so does the force. That is, F(t)=m(t)a(t)

At time t=10 seconds, the mass of an object is 82 grams and changing at a rate of 5gs. At this same time, the acceleration is 10ms2 and changing at a rate of −2ms3.

By the product rule, the force on the object is changing at the rate of

Please include units in your answer (click the link for help).. To enter compound units use multiplication, division, and exponent symbols, e. g., use ft∗lb for foot-pounds or m/s2 for meters per second per second.

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
