Amodel air rocket with a mass of 50.g is free to travel along a horizontal track. it begins from rest. after 2.0s, the rocket has lost 10% of its mass by expelling air at an average velocity of 53.m⋅s−1. what is the velocity of the rocket at that moment

(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.)
