Consider a head-on collision between two particles of masses m1 and m2

1.	Consider a head-on collision between two particles of masses m1 and m2.The initial speeds of the particles are u1 and u2 in the same direction.The collision starts at t=0 and the particles interact for a time interval △t.During the collision,the speed of the first particle varies as v(t)=u1+t△t(v1−u1).
Answer» Consider a head-on collision between two particles of masses $m_{1}$ and $m_{2}$ .The initial speeds of the particles are $u_{1}$ and $u_{2}$ in the same direction.The collision starts at t=0 and the particles interact for a time interval $△ t$ .During the collision,the speed of the first particle varies as $v (t) = u_{1} + \frac{t}{△ t} (v_{1} - u_{1}) .$

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
