A stone is thrown vertically with a speed of 5m/s. It came back to thrower in 20sec. Calculate the maximum height it reaches

Hi There Buddy!

Lets make use of the equations of motion to solve this problem.

We know time of flight is 2u/g

===> 2u/10 = 20 > u = 100 m/s

Now, we know the initial velocity, we have to find the maximum height.

H = (u^2)/2g = 10^4 / 20 = 500 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.

asthenosphere and convection
