A man runs at a speed of 4 m/s to overtake a standing bus. When he is 6m behind the door (t=0), the bus moves forward and continues with a constant acceleration of 1.2 m/s^2. How long does it take for the man to gain the door?

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied
