2. Two objects are connected by a massless string that passes over a frictionless pulley as shown in the diagram below. If the mass of the hanging object is 5 kg, answer the following: (a) how much must the mass of the object on the ramp be in order for both objects to be at rest? Assume there is no friction on the ramp. (b) if the object on the ramp has a mass of 7kg, find the magnitude of the acceleration that the blocks experience. (c) if we assume the ramp is not frictionless, what would the coefficient of static friction between the ramp and block need to be in order for the blocks to remain stationary, given the masses in part (h)? 30

You want to hang an object from the ceiling of an elevator that has a maximum acceleration of 4.0 m/s2. a) If you hang the object with a fishing line that supports 45 N of force, what is the maximum mass the object can have if the line is not to break? Please answer in units of kg.
Newton's 2nd Law can be symbolized as EF = ma Let mass A = 100 kg Let mass B = 1 kg What is true about an object of large mass versus an object of small mass? The more massive object has more inertia. The objects have the same inertia. The more massive object has less inertia. The objects have the same weight near Earth's surface. The more massive object has a larger weight near Earth's surface. V If the same net force is applied to both then the larger mass has the larger acceleration. O If the same net force is applied to both then the objects will haye the same acceleration. O If the same net force is applied to both then the larger mass has the smaller acceleration.
