A mass m₁ = 9.00 kg is connected by a light string that passes over a pulley of mass M = 14.0 kg to a mass m₂ = 12.5 kg sliding on a horizontal frictionless surface (see figure). There is no slippage between the string and the pulley. What is the magnitude of the tension that is acting on mass m₂? (The moment of inertia of the pulley is ½/Mr².)

Is it possible for an object with small mass to have a large momentum? a. Nonsense, objects have to be massive to have momentum. Ob.Nonsense, there is not enough mass. Oc. Yes, objects with low mass can have a lot of momentum if these are moving fast. Od. Yes all objects have momentum as long as they are moving. A Moving to another question will save this response.
