A careless driver in a sedan with a mass of 1250 kg speeding at 24 m/s hits a slow moving truck with a mass of 16,250 kg moving at 10 m/s. The impact causes the truck to speed up to 12 m/s. a. Calculate the final velocity of the sedan after the collision b Is this an elastic or inelastic collision?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

If y gets smaller as x gets bigger and y have an relationship?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
