Determine the roots of f(x)-0.6x2 2.4x +5.5 a)-using the quadratic formula, b)-using three iterations of the bisection method for the highest root. employ initial guesses of xl-5 and xu-10. compute the estimated error e and the true error e at each iteration.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
