The speed of escalator can be calculated as,
Relative velocity
Therefore total time required to take the person to get to the top

Carole is very tired and makes coffee. Newton would say that she must use her hand to pick up the cup, because an object at rest will stay at rest unless acted upon by an external force. <em>(B)</em>
In space we feel weightlessness because the earths gravity has less effect on us.The Earths gravitational attraction at those altitudes is only about 11% less than it is at the Earths surface. If you had a ladder that could reach as high as the the shuttles orbit, your weight would be 11% less at the top.
