QUESTION 17
A cart with mass 340 g moving on a frictionless surface at an initial speed of 1.2 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the
collision, the first cart continues in in its original direction at 0.66 m/s. The mass and final speed of the second cart, respectively, are:
OA. 173 g and 0.93 m/s
OB.99 g and 1.9 m/s
OC. 99 g and 0.64 m/s
OD. 109 g and 0.93 m/s
OE. 239 g and 1.9 m/s
