This question is typical on some driver's li- cense exams: A car moving at 41 km/h skids
14 m with lockexi brakes.
How far will the car skid with locked brakes
at 102.5 km/h? Assume that energy loss is
due only to sliding friction.
Answer in units of m.

The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?

What is the relationship between the direction of motion of the balloon and the wind currents

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
