A car leaves an intersection traveling west. Its position 4 sec later is 26 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position 4 sec later is 26 ft from the intersection. If the speeds of the cars at that instant of time are 12 ft/sec and 10 ft/sec, respectively, find the rate at which the distance between the two cars is changing. Round to the nearest tenth if necessary.

Solve.Two particles, m1 and m2, collide in a head-on, one-dimensional, elastic collision. If the first particle had an initial speed of 1 m/sec and the second particle was initially at rest, then the final speeds of the two particles, v1 and v2 (in m/sec), are as follows: v1 = 
v2 =
