2. In Fig. 2-7 a mass m of 12.00 kg is pulled, at constant speed, along an inclined plane which makes an angle with the horizontal. (a) What is the value of angle theta if we want to raise the mass m to a height of h = 2.00 m? (b) What is the mechanical advantage produced by the inclined plane? We assume that the inclined plane is frictionless.
