20 m/s^2 means that every second the velocity increases by 10 m/s. ie, 0,10,20,30,40 etc

Answer:

It is actually an answer to a question. It has to do with acceleration due to gravity. To understand it more, solve work, energy and time. Search it online. God will help u

Acid rain is rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.

If the mass of an object increases, the force acting on it, such as gravitational force, also increases

brainly a child on a swing set swings back and forth with a period of 3.3 s and an amplitude of 25°. what is the maximum speed o

beks73 [17]

Maximum speed of the child as she swings is 2.23 m/s.

<h3>Step by Step Calculation:</h3>

T=3.3 s is the oscillation's time period.

The swing's greatest angle is 25° (max).

The swing's bottom will have the following kinetic energy:

k=12mv2...........(1)

The mass in this situation is m, and the speed is v.

The potential energy change is expressed as,

∆U=mgL1-cosθmax...............(2)

Here, L is a string's length and g is the acceleration caused by gravity. L is given as,

L=gT24π2

Combine equation (1) with (2)

12mv2=mgL1-cos, maxv=2g, maxv=gT24, maxv=g2T22, maxv=9.8 m/s

22.33 m/s, 22.31 s22.31 cos25°

Therefore, the child's top speed is 2.23 m/s.

<h3>What is Oscillation ?</h3>

The process of any quantity or measure fluctuating repeatedly about its equilibrium value in time is known as oscillation.
A periodic change in a substance's value between two values or around its central value is another way to define oscillation.

In outer space a five KG object moving in to the right at 4M/S and a two KG object moving to the left at 3MS collide and stick t

Anettt [7]

Answer:

Combined speed, V = 2 m/s

Explanation:

Given that,

Mass of object 1, m = 5 kg

Speed of object 1, u = 4 m/s (due right)

Mass of object 2, m' = 2 kg

Speed of object 2, u' = -3 m/s (due left)

<em>Let V is the speed of the objects after the collision. Here, both objects stick to each other. Therefore, the momentum remains conserved. So,</em>

$mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{5\times 4+2\times (-3)}{(5+2)}\\\\V=2\ m/s$

So, the combined speed of the masses will be 2 m/s.
