On a horizontal frictionless surface block A (mass 3.00 kg) is sliding toward the east with speed VA and Block B (mass 5.00kg) is sliding toward the north with speed VB. After the collision block B is sliding toward the north with speed 2.00 m/s and block A is sliding with a speed of 6.00 m/s in a direction of 30.0° north of east, as shown in the sketch. What are the speeds VA and VB of the two blocks before the collision?
Ans. VA =
Ans. VB =
