The system shown in figure is released from rest at t= 0.Block A hits pulley at `t=t_(1)`and B hits the wall at `t=t_(2)`.If pulley is light and friction is absent,then

1) `t_1` < `t_2`

2) `t_1>t_2`

3) `t_1=t_2`

4) None of these

If the normals at points t_1 and t_2 meet on the parabola, then (a) t_1t_2=1 (b) t_2=-t_1-2/(t_1) (c) t_1t_2=2 (d) none of these

A train accelerates from rest at a constant rate a for time t_(1) and then it retards at the constant rate b for time t_(2) then comes to rest. Find the ratio t_(1) / t_(2) .

In the following figure, the pulley is massless and frictionless. The relation between T_(1), T_(2) and T_(3) will be :-

If the normal at t_(1) on the parabola y^(2)=4ax meet it again at t_(2) on the curve then t_(1)(t_(1)+t_(2))+2 = ?

If the normals drawn at the points t_(1) and t_(2) on the parabola meet the parabola again at its point t_(3) , then t_(1)t_(2) equals.

The stress-strain graph for a metallic wire is shown at two different temperature, T_(1) and T_(2) which temperature is high T_(1) or T_(2) ?

A system is at rest as shown in figure. The tension in the string in T_(1) . When the 2 kg block is removed, the system moves with some acceleration a and tension in string becomes T_(2) Find T_(1)//T_(2) .

T_(1) and T_(2) in the given figure are

Calculate T_(1) & T_(2) .

A tank full of water has a small hole at its bottom. Let t_(1) be the time taken to empty first one third of the tank and t_(2) be the time taken to empty second one third of the tank and t_(3) be the time taken to empty rest of the tank then (a). t_(1)=t_(2)=t_(3) (b). t_(1)gtt_(2)gtt_(3) (c). t_(1)ltt_(2)ltt_(3) (d). t_(1)gtt_(2)ltt_(3)
