No
Step-by-step explanation:
they could be but it doesnt say where the angle is so there isn't enough information to tell if they are congruent. answer is no
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.
15x1000+4x100+9x1
I belive that is edpanded notation.
