A23.0 kg block at rest on a horizontal frictionless air track is connected to the wall via a spring. the equilibrium position of the mass is defined to be at x=0. somebody pushes the mass to the position x= 0.350 m, then lets go. the mass undergoes simple harmonic motion with a period of 4.10 s. what is the position of the mass 3.403 s after the mass is released?

Explanation:

We use the harmonic motion position equation:

where A = 0.350 and for t = 0

so:

and also:

so we have:

x(t)=0.350cos(1.532 t)

For t = 3.403 s

x(3.403)=0.350cos(1.532 (3.403)) = 0.348 m

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.
