An automobile of mass M=5400 kg is moving at a speed of 30 m/s The engine is disengaged suddenly at t= 0 sec. Assume that the equation of motion after t=0 is given by dv 5400 v dx -8.276 v2 – 2000 Where v= v(t) is the speed (m/sec) of the car at t. The left side represents Mv (dv/dx).The first term on the right side is the aerodynamics drag, I|||||| II||\|and the second term is the rolling resistance of the tires. Calculate how far the car travels until the speed reduces to 15 m/sec.(hint: the equation of motion may be integrated as 30 5400 v dv E dx = x 15 8.276 v2+2000 Evaluate the preceding equation using Simpson rule).
