99 points i will give brainliest answer! explain answer! a squirrel sees a big acorn being thrown from a tree by a chipmunk and attempts to snatch it. the acorn is thrown from a 10.0 m high branch and with a horizontal velocity of 1.1 m/s. the squirrel on the ground is 5.0 m from the base of the tree. what is the of the squirrel’s average velocity if it grabs the acorn in its mouth just as it touches the ground?

Answer from: Annlee23

Since the acorn is thrown horizontally, the initial vertical velocity is 0 m/s. Let’s use the following equation to determine the time to fall 10 meters.

d = vi * t + ½ * a * t^2, vi = 0, a = 9.8
10 = 4.9 * t^2
t = √(10/4.9)
This is approximately 1.43 seconds. Let’s use the following equation to determine the horizontal distance it moves.

d = v * t = 1.1 * √(10/4.9)
This is approximately 1.57 meters. To determine the horizontal distance between the acorn and squirrel, subtract this distance from 5 meters.

d = 5 – 1.1 * √(10/4.9)

This is approximately 3.83 meters. To catch the acorn, the squirrel must move this distance in the same time as the acorn falls 10 meters.

Average velocity = ([5 – 1.1 * √(10/4.9] ÷ √(10/4.9) = 2.4 m/s

I hope this helps you to understand how to solve this type of problem.

Hello!

For big answers like this I write it down on a piece of paper but I don't know how to put it into my answer :/

The average velocity of the squirrel is 2.4 m/s.

I hope it helps!

Answer from: Quest

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic = - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
