1.	A body is moved along a straight line by a machine delivering a constant power. The distance moved by the body in time t is proportional to
Answer» EXPLANATION: Let's consider a body is moved ALONG a straight line by a machine delivering a constant power P. The DISTANCE moved by the body is S. Power, P=F.v.. . . . . . (1) Force, F=ma . . . . . . . .(2) where, v= t S ACCELERATION, a= t 2 S m= mass from equation (1) and equation (2), we get P= t 2 mS × t S S 2 = m Pt 3 From the above equation, we get S 2 ∝t 3 S∝t 3/2
