Un autobuz merge prin oras patru statii drumul total fiind de 4 km. prima statie reprezinta doua zecimi (2/10) din drumul total, a doua statie mai mica cu 3 hm decat prima , a treia estr cu 2 dam mai mult de cat jum din restul drumului. ce lungime are fiecare statie?

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final

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.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
