Solve the formula for v 1 Average acceleration of an object a= v 1 -v 0 t

In this question , we have the formula of acceleration given, which is

And we have to solve for

First we need to get rid of denominator t from right side and for that, we multiply both sides by t, that is

Now to solve for v1 , we need to get rid of v0, and for that , we add v0 to both sides, that is

And that's the required answer.

v^2=0^2 + 2(-9.3)(-3.5)

v=vy=the square root of 65.1= 8.1 m/s

Explanation:

v^2=0^2 + 2(-9.3)(-3.5)

v=vy=the square root of 65.1= 8.1 m/s

Explanation:

The answer is in the image 

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
