A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is
Given veca = hati-hatj+hatk and vecb = 2hati-4hatj-3hatk , find the magnitude of veca
A body of mass 2kg is moving with a velocity of vecu=3hati+4hatj m//s .A steady force vecF=hati-2hatj N begins to act on it. After four second, the body will be moving along.
A small sphere of mass m =2kg moving with a velocity baru = 4hati - 7hatj m//s colides with a smooth wall and returns with a velocity barv = -hati + 3hatj m//s . The magnitude of the impulse received by the ball is .
