A ball is released at the point x=2m on an inclined plane with a nonzero initial velocity.?
A ball is released at the point x=2m on an inclined plane with a nonzero initial velocity. After being released, the ball moves with constant acceleration. The acceleration and initial velocity of the ball are described by one of the following four cases:
case 1, a>0,v0>0;
case 2, a>0,v0<0;
case 3, a<0,v0>0;
case 4, a<0,v0<0.
1) In which of these cases will the ball definitely pass x=0 at some later time?
2)In which of these cases is more information needed to determine whether the ball will cross x=0?
3)In which of these cases will the ball come to rest momentarily at some time during its motion?
Answer:
This is the Best Answer for A ball is released at the point x=2m on an inclined plane with a nonzero initial velocity.?
1) Cases 3 and 4, with a<0, will result in the ball passing x = 0 eventually.
2) Case 2, with a>0 and v<0, is ambiguous.
3) Cases 2 and 3, where a and v have different signs, require the velocity to eventually change sign, meaning it will momentarily come to rest.
