3 objects with masses m1=5kg, m2=10kg and m3=15kg are attached by massless string over two frictionless pulleys. The horizontal surface is frictionless and system is released from rest. Using energy concept calculate m3 speed after it has moved down 0.4m

Let 𝑣(𝑡) = 𝑡 2 − 2𝑡 be the velocity, in 𝑓𝑡⁄𝑠𝑒𝑐, of an object at time 𝑡, in seconds. a. What is the initial velocity, 𝑣(0)? b. When does the object have a velocity of zero? c. What is the meaning of the quantity 𝑣(3)? What are its units
