Q.1 A body is moved along a str. line by a machine delivering a constant power . The distance travelled by the body in time t is proportional to - t ^3/4
- t^3/2
- t^1/4
- t^1/2 Q2. The potential energy of a 1 kg particle free to move along the x – axis is given by ( X^4/4 – X^2/2) ,then the maximuim speed in m/s is a 3/ squareroot 2 b. 2^ ½ c. 2
