Question

A block of mass m. - 4 kg and a block of mass m2 = 6 kg are connected to each other by a light cord that passes
over a frictionless pulley of mass m3 = 0 kg. One mass rests on a fnctionless table and
the other hangs from the pulley.
How
fast will the mass m. be moving after the m2 mass has fallen a distance 0.5
m from rest?​

Answer 1

Answer:

m2gh= (1/2)mv^2

or v^2=√21
