1.	A solid horizontal surface is covered with a thin layer of oil. A rectangular block of mass m=0.4 kg is at rest on this surface. An impulse of 1.0 N s is applied to the block at time to t=0 so that it starts moving along the x-axis with a velocity v(t)=v0e−tτ, where v0 is a constant and τ=4 s.

Answer» A solid horizontal surface is covered with a thin layer of oil. A rectangular block of mass $m = 0.4 k g$ is at rest on this surface. An impulse of $1.0 N$ s is applied to the block at time to $t = 0$ so that it starts moving along the x-axis with a velocity $v (t) = v_{0} e^{\frac{- t}{τ}}$ , where $v_{0}$ is a constant and $τ = 4 s$ . The displacement of the block, in metres, at $t = τ$ is . [Take $e^{- 1} = 0.37$ ]

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
