A 1.0 Kg object, A, with a velocity of 4.0ms-1 to the right, strikes a second object, B, of mass 3.0 Kg, originally at rest. In the collision, A is deflected

from its original direction through an angle of 50°; its speed after the

collision is 2.0ms-1. Find the angle between B’s velocity after the collision

and the original direction of A, and find the speed of B after collision​

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
