The position of a particle moving under uniform accel-eration is some function of time and the acceleration.22. AtaSuppose we write this position as x = ka e, where k is adimensionless constant. Show by dimensional analysisthat this expression is satisfied if m 1 and n 2. Canthis analysis give the value of k? =14.

Why is the following situation impossible? A student's dor-mitory room measures 3.8 m by 3.6 m, and its ceilingis 2.5 m high. After the student completes his physicscourse, he displays his dedication by completely wall-papering the walls of the room with the pages from his2.

Dimension of length is L and dimension of time is T.
