During the construction of an office building, a hammer is accidentally dropped from a height of 784 ft. the distance (in feet) the hammer falls in t sec is s = 16t2. what is the hammer's velocity when it strikes the ground?

The hammer's velocity when it strikes the ground is 128 ft/s.

Explanation:

Given that,

The distance (in feet) the hammer falls in t sec is given by the relation as :

The hammer is accidentally dropped from a height of 784 ft. We need to find the hammer's velocity when it strikes the ground. We know that the velocity of an object is equal to :

When the hammer strikes ground, s = 256 ft

So,

So, the velocity of the hammer when it strikes the ground is given by :

So, the hammer's velocity when it strikes the ground is 128 ft/s. Hence, this is the required solution.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
