Two objects are dropped from rest from the same height. object a falls through a distance da and during a time t, and object b falls through a distance db during a time 2t. if air resistance is negligible, what is the relationship between da and db? da=1/4dbit cannot be determined from the information given. da=4dbda=2dbda=1/2db

Da=(1/4)Db

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

When s = Da, t = t

When s = Db, t = 2t

Dividing the two equations

Hence, Da=(1/4)Db

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.
