Question

when a piece of rock stone falls on the ground from a height, it makes deeper impression. Give reasons.​

Answer 1

Answer:

We can use the formula S=ut+(1/2)at2

Where u is initial velocity, ‘s’ is distance travelled (Height of the tower in this case), ‘t’ is time travelled and ‘a’ is the constant acceleration.

So , here as the object is dropped , the initial velocity ,u is 0

Acceleration is the acceleration due to gravity ‘g’ which is constant and has value of 9.8m/s2

Time travelled is given as t=10 seconds

Substituting the values in the equation s=ut+(1/2)at2we get

s=0 * 10 + (1/2)* 9.8 * 10 *10

s=490 meters

So, the height of the tower is 490 meters

Answer 2

Answer:

if an object is fallen dow from a height it forms an impression because of the speed of the object

Explanation:

if we throw a objrect from 3 m the impression and speed will be reduced an if we throw from 5 km the impression will be more and the speed will be higher
