The SI unit of energy is J = kg m2 s-2; that of speed v is m s-1 and of acceleration a is m s -2. Which of then formulae for kinetic energy (k) given below can you rule out on the basis of dimensional arguments (m stand for the mass of the body)? (a) K = m2v3 (b) K = (1/2) mv2 (c) K = ma (d) K = (3/16) mv2 (e) K = (1/2) mv2 + ma

Consider a simple pendulum, having a bob attached to a string that oscillates under the action of the force of gravity. Suppose that period of oscillation of the simple pendulum depends on its length (l), mass of the bob (m) and acceleration due to gravity (g). Derive the expression for its time period using method of dimensions.

A car is moving along a straight line, say OP in fig 3.11. It moves from O to P in 18 s and return from P to Q in 6.0 s. What are the average velocity and average speed of the car in going (a) from O to P and (b) from O to P and back to Q ?
