A projectile is launched vertically from the earth with speed \(v_1\) hits a satellite at the height \(h\) moving with speed \(v_2\). If both have the same mass \(m\), then what is the common velocity if they move together after the collision?
A particle of mass \(10 \mathrm{~kg}\) moving eastwards with a speed \(10 \mathrm{~m} / \mathrm{s}\) collides with another particle of the same mass moving northward with the same speed \(10 \mathrm{~m} / \mathrm{s}\). The two particles coalesce on collision. The new particle of mass \(20 \mathrm{~kg}\) will move in the north-east direction with velocity.
