Billiard ball collision in 2-D. Billiard ball A moving with speed vA= 2.5-m/s in the +x direction strikes an equal-mass ball B initially at rest. The two balls are observed to move off at 40° to the x axis, ball A above the x axis and ball B below. That is, θA = 40° and θB = -40° What are the speeds of the two balls after the collision? b) Billiard ball collision in 2-D. Billiard ball A moving with speed vA= 3.1-m/s in the +x direction strikes an equal-mass ball B initially at rest. The two balls are observed to move off at 27° to the x axis, ball A above the x axis and ball B below. That is, θA = 27° and θB = -27° What are the speeds of the two balls after the collision? c) Billiard ball collision in 2-D. Billiard ball A moving with speed vA= 5.1-m/s in the +x direction strikes an equal-mass ball B initially at rest. The two balls are observed to move off at some unknown angle to the x-axis, ball A above the x-axis and ball B below. If v'A = 6.32-m/s at what angle did ball A go above the x-axis? d) Billiard ball collision in 2-D. Billiard ball A moving with speed vA= 7.1-m/s in the +x direction strikes an equal-mass ball B initially at rest. The two balls are observed to move off at some unknown angle to the x-axis, ball A above the x-axis and ball B below. If v'A = 6.34-m/s at what angle did ball A go above the x-axis?
