Answer:
They hit the ground at the same time
Explanation:
Mass doesn't matter in free fall. As long as they were released with the same velocity and the same height, they'll hit the ground at the same time
The change in energy after the collision is <u>0.5</u>
<u />
<h3>What is change in energy?</h3>
This refers to the difference in the energy where energy is the capacity to do work. There different forms of energy they include mechanical energy, solar energy, electrical energy and so on.
The energy described in the problem is mechanical energy and it is of two types kinetic energy and potential energy
<h3>solving for the change in energy as a result of the collision</h3>
where mass of particle mp = 4 kg
mass of object mb = 6 kg
force constant of spring k = 100 N/m
amplitude A = 2 m
kinetic energy = 1/2 mv^2
initial velocity u = Aω
ω = sqrt ( 100/ 4 )
u = 2 sqrt ( 100/ 4 )
u = 10m/s
final velocity v = 5 m/s
change in energy
= - 0.5 * ( 4 + 4 ) * 5^2 + 0.5 * 4 * 10^2 ) / 0.5 * 4 * 10^2
= 0.5

Answer:
The gallon of milk is placed at a distance of 0.641 meters.
Explanation:
We have,
Mass of two 0.6 kg cartons of cereal is 1.2 kg
Length of the basket, l = 0.77 m
Center of the basket is 0.385 m
Mass of the half gallon of milk is 1.8 kg
Total weight in the basket is 1.2 + 1.8 = 3 kg
We need to find the position of the gallon of milk so that the center of mass (COM) of your groceries is at the center of the basket.
So,
(3 × 0.385) = (1.2 × 0) + (1.8 × x)
1.155 = 1.8 x
x = 0.641 meters
So, the gallon of milk is placed at a distance of 0.641 meters.
because i said so
the answer is 80 diveded by 8 equalzzzz
