A particle is projected from a tower of height $40\ m$ in horizontal direction. Due to wind a constant acceleration is provided to the particle opposite to its initial velocity. If particle hits the ground (at the bottom of the tower) at an angle $37^o$ with horizontal, then find acceleration provided by wind to the particle 
A person brings a mass of $1 \ kg$ from infinity to a point $A .$ Initially the mass was at rest but it moves at a speed of $2 \mathrm{~ms}^{-1}$ as it reaches $A .$ The work done by the person on the mass is $-3 J$ . The potential at $A$ is:

An asteroid is moving directly towards the centre of the earth. When at a distance of $10 \mathrm{R}$ ($R$ is the radius of the earth) from the earths centre, it has a speed of $12 \;\mathrm{km} / \mathrm{s}$. Neglecting the effect of earths atmosphere, what will be the speed of the asteroid when it hits the surface of the earth (escape velocity from the earth is $11.2 \;\mathrm{km} / \mathrm{s}$ ) $?$
