# Prisms in mechanics

Level pending

Two right-triangle prisms are placed on a horizontal surface as depicted. Prism m2 starts to slide down with zero initial velocity on the hypotenuse of prism m1 due to gravity. Neglect all friction. What is the displacement in centimeters of prism m1 in respect to the ground when prism m2 has reached the ground? Note: Write the number only. For example, if your answer is 12 cm, write 12. a = 30 cm, b = 10 cm, m1 = 300 g, m2 = 200 g.
