Afalling object accelerates from -10.0 m/s to -30.0 m/s. how much time does it take?

2.04 s

Explanation:

v = at + v₀

(-30.0 m/s) = (-9.8 m/s²) t + (-10.0 m/s)

t = 2.04 s

Answer:

The time taken by the falling object is 2.04 sec

Solution:

The initial velocity

The final velocity

Let us assume that the time taken is t sec

We know that the acceleration due to gravity

As per the free falling object motion,

So, it takes total 2.04 sec

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
