1.	A stream of particles of mass m and separation d hits a perpendicular wall with a velocity v_(0) and rebounds along the original line of motion with a velocity v. The mass per unit length of the incident stream is lambda = (m)/(d). The the force exerted by the stream on the wall is
Answer» `LAMBDA V (v_(0) + v)` `lambda v (v_(0) - v)` `lambda v_(0) (v_(0) - v)` `lambda v_(0) (v_(0) + v)` ANSWER :D
