Question
If a force of 20 N is applied to push a 4 kg object,
what is the acceleration produced? ÂSolution
Using Newton's Second Law: F = ma a = F/m = 20 / 4 = 5 m/s²  This show how force changes motion.  This law is crucial for calculating effects of force on mass.
Solve for x in the equation: 3(x + 2) + 2(2x - 5) = 5x + 9
If x = 19, then the value of x5 - 20x4 + 20x3 - 20x2 + 20x - 1 is
