A 40 kg girl and an 8.4 kg sled are on the frictionless ice of a frozen lake, 15 m apart but connected by a rope of negligible mass. The girl exerts a horizontal 5.2 N force on the rope. What are the acceleration magnitudes of a (a) the sled and (b) the girl? (c) How far from the girl's initial position do they meet?

a) , b) , c)

Explanation:

a) The acceleration magnitude for the sled is:

b) The acceleration magnitude for the girl is:

c) The position equations for the girl and sled are, respectively:

It is needed to know in which time the girl and sled meet each other. That is:

The final position in comparison with the initial position of the girl is:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
