Question 1.4: Show that the correct expressionv = V + at is dimensionally correct, where v and vo represent velocities, a is the acceleration and t is a time interval. Question 1.5: Suppose we are told that the acceleration of a particle moving in a circle and of radius r with uniform velocity v, is proportional to some power of r, say r", some power of v, say v. How can we determine the powers of r and v? Question 1.6: Show that the expression x = vt + at2 is dimensionally correct, where x is a coordinate and has units of length, v is velocity, a is acceleration andt is time. 21 Question 1.7: Newton's law of universal gravitation is given by Mam
