Given,
Rate of free fall = 216 km/h
Solution,
km/h to m/s is converted as follows :

So, the rate of fall is 60 m/s.
If t = 20 s
Assume, initial velocity = 0
It will move under the action of gravity.
Using equation of motion,

Hence, this is all for the solution.
There is no solution since 5 doesn't equal 45
18 ? am not really sure tho its kinda difficult lol
Personification is when an inanimate object is given human-like qualities in writing, so of the options in question 6, the choice with personification in the sentence would be b. because the World Trade Center does not have footprints, humans do! :)
