Aspring is used to launch a coffee mug. the 20 cm long spring can be compressed by a maximum of 8 cm. the mug has a mass of 300 g. what kind of spring do you need to launch the mug at least 2 stories high (5 m) - as measured from the relaxed spring position - using the maximum compression? n/m

k=4593.75

Explanation:

Given

length of spring =20 cm

maximum compression in spring is x=8 cm

mass of mug m=300 gm

maximum height to which cup is needed to raise is h=5 m

By conserving Energy i.e. Elastic Potential Energy will be converted in to Potential energy of cup

where

so we should use a spring with spring constant k=4593.75 N/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.
