If it takes 6 sec for a ball to strike the ground when it it is released from rest, determine the height in meters of the building from which it was released. take (g - acceleration due to gravity to be 10 m/sec) 60 m 120 m 140 m 180 m

The height of the building is 180 meters.

Explanation:

It is given that,

Time taken for a ball to strike the ground, t = 6 sec

It is released from the rest. We need to find the height of the building from which it is released. It can be calculated using the equation as follows :

Here, a = g and u = 0

So,

s = 180 meters

So, the height of the building is 180 meters. Hence, this is the required solution.

it is called kinetic energy

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
