Acar starts from rest at a stop sign. it accelerates at 4.0 m/s^2 for 3 seconds, coasts for 2 s, and then slows down at a rate of 3.0 m/s^2 for the next stop sign. determine the distance between the two stop signs.

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

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.
