Sample questions

1. 1.A body is moved along a straight road by a machine delivering constant power. The distance moved by the body in time t is proportional to
   • A.t^(3/4)
   • B.t^(3/2)
   • C.t²
   • D.t^(1/2)
2. 2.A body possesses kinetic energy of 'X' J. If the mass of body increases 49 times determine its final velocity if Kinetic energy remains constant.
   • a.$1/\mathrm{X}$ the original velocity.
   • b.$1/5^{\text{th}}$ the original velocity
   • c.$1/2$ the original velocity
   • d.$1/7^{\text{th}}$ the original velocity
3. 3.The bullet weighing $100\,\mathrm{g}$ is released from the barrel of an air gun with a velocity of $4\,\mathrm{ms}^{-1}$. Calculate the potential energy of the spring?
   • a.8 J
   • b.$0.8\,\mathrm{J}$
   • c.800 J
   • d.$0.08\,\mathrm{J}$
4. 4.Is it possible that no transfer of energy takes place even when a force is applied to a body?
   • A.Yes, when the force is parallel to the displacement of the body.
   • B.Yes, when the force is normal to the displacement of the body (e.g., a vertical force on a horizontally moving frictionless surface).
   • C.No, energy transfer always occurs whenever a force is applied.
   • D.Yes, but only if the body is at rest and no displacement occurs.
5. 5.An ox can apply a maximum force of $1000\,\mathrm{N}$. It is taking part in a cart race and is able to pull the cart at a constant speed of $30\,\mathrm{m\,s^{-1}}$ while making its best effort. Calculate the power developed by the ox.
