Astone is thrown horizontally at 15 m/s from the top of a cliff 40 meters high. how far from the base does the stone hit the ground? pls

She stone hit ground 42.86 m far from base of cliff.

Explanation:

  Initial height from ground = 40 meter.

We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this the velocity of body in vertical direction = 0 m/s, acceleration = 9.8 , we need to calculate time when s = 40 meter.

Substituting

So it will take 2.86 seconds to reach ground.

So, stone travels horizontally at 15 m/s for 2.86 seconds.

Distance travelled = 15 x 2.86 = 42.86 m

So, the stone hit ground 42.86 m far from base of cliff.

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.
