A car traveling east and a minivan traveling south collide in a completely inelastic collision at a perpendicular intersection. If the initial speed of the 1500kg car was 80.0km/h and the initial speed of the 3000kg minivan was 46.0km/h, what is the speed of the vehicles immediately after collision? What is the direction of the velocity of the vehicles immediately after collision?
suppose that a projectile which is subject to a linear resistive force is thrown down with a speed of Vyo which is greater than the terminal speed Vterm. Describe and explain how the velocity varies with time, and make a plot of Vy against t for t..
