An amusement park ride travels up and down. The vertical position of the
ride in meters over
time is shown below.

what is the displacement of the ride between 0 s and 16 s ?

what is the distance traveled between 0 s and 16 s ?

PLEASE HELPP

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
