1what is length of the hill slide??? or do we have to give a generalised ans or is the time given neither is the angle??
Two children stand on a large, sloping hillside that can be considered as a plane. The ground is just sufficiently icy that a child would fall and slide downhill with a uniform speed as the result of receiving even the slightest impulse.
For fun, one of the children (leaning against a tree) pushes the other with a horizontal initial speed v0=1m/s. The latter slides down the slope with a velocity that changes in both magnitude and direction. What will be the child’s ï¬nal speed if air resistance is negligible and the frictional force is independent of the speed?

71Initial Velocity is given and friction has no work!! So I think that angle that is given there 'a' has some clue!
