Question

:Plot the following coordinate points on a plane.
a.A(2,3) b.M(4,0)
Hey guys pls help my brother in these questions pls if u will give correct answer i will mark u as brainliest and if u give useless question i will report ur answer......​

Answer 1

Answer:

A = x = 2

y = 3

in 1st cood......

&

M = x = 4

y = 0

on line x .

point on 4 in positive.

ok

PLS FOLLOW ME GUY'S.

I have given answer of 1st question also ........

tell to your brother this is so nice site for education.

in this app there is nothing else dirty ok............

take care...

Answer 2

Step-by-step explanation:

Answer:

Given :-

Mass of object = 100 kg

Initial velocity = 5 m/s

Final velocity = 8 m/s

Time taken = 6 sec

To Find :-

Mounmentum

Magnitude

Force exerted

Solution :-

As we know that

\huge \tt \: P = mvP=mv

Here,

P denotes Mounmentum

M denotes Mass

V denotes Velocity

Firstly let's calculate initial Mounmentum

\huge \fbox{PI = mu}

PI = mu

Here,

PI = Initial Mounmentum

M = Mass

U = Initial Mounmentum

\tt \: PI = 100 \times 5PI=100×5

\tt \: PI = 500 \: mpsPI=500mps

Now,

Let's find final Mounmentum

As we know that

\huge \fbox{PF = mv}

PF = mv

Here,

PF = Final Mounmentum

M = Mass

V = Final Mounmentum

\tt \: PF = 100 \times 8PF=100×8

\tt \: PF = 800 \: mpsPF=800mps

Now,

Let's find Acceleration

\huge \boxed{ \bf \: A = \dfrac{v - u}{t}}

A=

t

v−u

Here,

A = Acceleration

V = Final Mounmentum

U = Initial Mounmentum

T = Time

\tt \: A = \dfrac{8 - 5}{6}A=

6

8−5

\tt \: A = \dfrac{3}{6}A=

6

3

\tt \: A = \dfrac{1}{2} \: = 0.5 \: mpsA=

2

1

=0.5mps

Now,

Let's find force exerted

\huge \fbox{F = ma}

F = ma

Here,

F = Force

M = Mass

A = Acceleration

\tt \: F = 100 \times 0.5F=100×0.5

\tt \: F = 50 \: NF=50N
