A 0.5 kg apple falls from a tree. When the apple is 1.5 meters above the ground it has a velocity of 2.4 m/s. What is the apple's total mechanical energy

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

(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.)

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
