Determine the velocity of the running man with respect to car A.

Physics

<u><em>Answer</em></u>: A) -55 km/h

<u><em>Explanation</em></u>: The running man is traveling at -55 km/hr with respect to Car A. If the man were standing still, the car would be passing at 50. Since he is traveling at 5 in the opposite direction, that direction is positive, to him. His velocity now adds to the car velocity (50 + 5), but negative to account for the opposite direction.

Hope this helps!

Find the energy in joules required to lift a 55.0 megagram object a distance of 500cm
pantera1 [17]

1,000 grams = 1 kilogram
so 55 megagrams = 55,000 kilograms

100 cm = 1 meter
so 500 cm = 5 meters

Acceleration of gravity on Earth = 9.8 m/s²

Weight = (mass) x (gravity)

========================================

Work = increase in potential energy =

               (weight) x (height) =

             (mass) x (gravity) x (height) =

             (55,000 kg) x (9.8 m/s²) x (5 m) =

                     2,695,000 joules .
