Two persons are not equally strong. One is weaker than another. They are going
to carry a wooden pole. Suggest them a way to carry the wooden pole in such a
way that the stronger person needs to apply more effort and the weaker person
needs to apply less force. Also explain the scientific reason behind your answer.

Which of the following is an example of motion in two dimensions?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
