Neglecting air resistance, the distance s left parenthesis t right parenthesis in feet traveled by a freely falling object is given by the function s left parenthesis t right parenthesisequals16 t squared, where t is time in seconds. the height of a certain tower is 862 feet. how long would it take an object to fall to the ground from the top of the building?

Explanation:

It is given that, the height of a certain tower is 862 feet i.e to reach on the ground the object should travel, s = 862 feet

The distance traveled by a freely falling object is given by :

t = 7.34 seconds

So, the object will take 7.34 seconds to fall to the ground from the top of the building. Hence, this is the required solution.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
