A particle of mass
m1 and speed
v1 (in the +x direction) collides with another particle of mass
m2 is at rest before the collision occurs, thus
v2=0. After the collision, the particles have velocities
v′1 and
v′2 in the x-y plane in the directions of
θ1 and
θ2 with the x-axis (see figure). There re two external forces. Express all out answers in terms of
m1,m2,v1,θ1 and
θ2(a) What is the total momentum before the collision (direction and magnitude)
(b) What is the total momentum after the collision (direction and magnitude)
(c) What is the total kinetic energy before the collision?
(d) What is the ratio of the speed
v′2v′1(e) What is the magnitude (speed) of
v′1, if
m1=m2?
