Question
a ramp on wheels with mb = 30 kg

Ball A, with mass mA- 15 kg and radius rA 0.2 m, initially travels to the right at vA1 30 m/s. A ramp on wheels with ms 30 kg and incline of 0 40° initially travels to the right at Ve1 10 m/s. Find the velocity of A and B immediately after the impact if the ramp can only ) A1 VB1 тв travel in the horizontal direction. Let e 0.4
