If you wanted to produce more power,what could you do to maximize power
PSYCHO15rus [73]

In physics, power is defined as energy per unit time.  You will also hear it described as work per unit time.  The standard unit of measure for power is the watt, where a watt is defined as joules (energy) per second (time).  This is expressed as a fraction as J/s.  If you wanted to increase the power in any operation, you can either increase the energy (more joules) or reduce the time (fewer seconds).

Answer:

v = 12.86 km/h

v = 3.6 m/s

Explanation:

Given,

The distance, d = 13.5 km

The time, t = 21/20 h

                  =  1.05 h

The velocity of a body is defined as the distance traveled by the time taken.

                                     v = d / t

                                        =  13.5 km / 1.05 h

                                        = 12.86 km/h

The conversion of km/h to m/s

                                   1 km/h = 0.28 m/s

                                     12.86 km/h = 12.86 x 0.28 m/s

                                                         = 3.6 m/s

Hence, the velocity in m/s is, v = 3.6 m/s
