An object thrown straight up falls back and is caught at the same place it is launched from. Its time of flight is T; its maximu

Natasha_Volkova [10]

Answer:

The average velocity for the second half of the trip is -2H/T

Explanation:

Given;

time of flight as T

maximum height as H

The maximum height of the flight is given by;

$H = \frac{1}{2}aT^2\\\\ a = \frac{2H}{T^2}\\\\ But \ average \ velocity \ is \ given \ by , v = aT\\\\v = (\frac{2H}{T^2} )T\\\\v = \frac{2H}{T} \ (This \ is \ the \ average \ velocity \ for \ the \ entire \ trip)\\\\During \ the \ second \ half \ of \ the \ motion, the \ height \ of \ travel \ is \ -H \ (negative \ direction)\\\\The \ time \ of \ travel \ is \ \frac{1}{2} \ of \ time \ of \ flight \ (T) = \frac{T}{2} \\\\The \ average \ velocity = \frac{-H}{T/2} = \frac{-2H}{T}$

Therefore, the average velocity for the second half of the trip is -2H/T

Please help!!!

larisa86 [58]

Answer:

Explanation:

mass of top book = 2kg

mass of book under = 3kg

mass of table = 20kg

a) The diagram is in the attached file to this solution

b) Since the objects are at rest, the acceleration of each of the object is zero

c) Force of gravity giving that g = 10 is

for the top book = 2*10 = 20N

for the book under = 3*10 = 30N

for the table = 25*10 = 250N

d) for the top book = 2*10 - 2*10= 0N

for the book under = 3*10 - 3*10 = 0N

for the table = 25*10 - 25*10 = 0N
