Answer:
517.5Ns
Explanation:
F=(MV - MU)/t
where MV - MU is the change in momentum,
therefore, MV - MU = Ft
= 345 X 1.
= 517.5Ns
Speed can be thought of as the rate at which an object covers distance. ... Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour........?
-- A motor and a generator both do a transformation between electrical energy and some other form of energy, but they do it in opposite directions.
-- A motor takes electrical energy and transforms it into mechanical energy, which can then be used to run mechanical things like cars or wheat grinders.
-- A generator takes mechanical energy ... like from a steam turbine or a windmill or a water wheel ... and transforms it into electrical energy, which can then be shipped over long distances through wires, and used to run motors or other electrical things.

Answer:
Work done on the two cart system is 2 N-m
Explanation:
Work done is equal to the product of force and displacement
Work done =4N * (0.17 +0.33)
work done = 4N * 0.5
Work done = 2 N -m
Work done on the two cart system is 2 N-m
