The system shown is released from rest and moves 80 cm. What is the final speed, if m₁ = 3kg, m₂ = 2kg, frictional surface with µ = 0.3, and pulley as solid disk with M = 1.5kg and R=0.3 m? m2 m1 A 3.5 kg ball is hanging from a long wire when it is struck by a 0.7-kg stone traveling horizontally to the right at 22.0 m/s. The stone rebounds to the left with a speed of 8.50 m/s, and the ball swings to a maximum height h above its original level. Find the value of h.
