Answer:
No
Step-by-step explanation:
10+8v-3v
Combine like terms
10 +5v
This is not equal to 18 -3v
I’m pretty sure the anser is b
Answer: the vaule is 4
Step-by-step explanation:
becusee its the same as the one across
I assume you are looking for the formula, and the velocity.
The formula:
v1^2-v0^2=2aS
where
v0=initial velocity (0 if object falls from rest), ft/s
v1=velocity reached after falling a distance S, ft/s
S=distance from initial position, positive downwards (for falling objects), ft
a=acceleration due to gravity, 32.2 ft/s^2 in imperial units
So substituting numbers, assuming initial velocity is zero (from rest), then
S=25 ft
v1^2-0^2=2*32.2*25
v1^2=1610
v1=sqrt(1610)
=40.1 ft/s

I think it's the last one! In an experiment, one group is studied over a short period of time---
