1.	A block of mass 1.9 kg is at rest at the edge of a table, of height 1 m. A bullet of mass 0.1 kg collides with the block and sticks to it. If the velocity of the bullet is 20 ms−1 in the horizontal direction just before the collision then the kinetic energy, just before the combined system strikes the floor, is [Take g=10 ms−2].

Answer» A block of mass $1.9 kg$ is at rest at the edge of a table, of height $1 m$ . A bullet of mass $0.1 kg$ collides with the block and sticks to it. If the velocity of the bullet is $20 {ms}^{- 1}$ in the horizontal direction just before the collision then the kinetic energy, just before the combined system strikes the floor, is [Take $g = 10 {ms}^{- 2}$ ]. Assume there is no rotational motion and losses of energy after the collision is negligible.

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
