1. When two bodies move uniformly towards each other, the distance between them diminishes by 25 mm in 'n' seconds. If the two bodies move with the same velocity but in the same direction, the distance between them increases by 8 cm in (n -1) seconds. Derive an expression for the velocity of each body. 2. A crate of eggs of mass 15.2 g is carried along a smooth horizontal surface with an initial speed Vo. A force of (45 newtons 15 minutes. i.e.(45(15/60))) is applied at the opposite direction of its motion. The force reduces the initial velocity Vo to 1/3 of its value while the body moves 14 mm. a. evaluate how long it takes for this to occur b. determine the values of the initial speed
