The accleration of a particle is ,

$a=\frac{v-u}{t}$

Put 50 for a, 3 for t, 0 for u in the equation implies,

$\begin{gathered} 50=\frac{v}{3} \\ v=150ms^{-1} \end{gathered}$

Therefore, the answer is 150m/s.

Answer:

49 = 0 +9.8t
t = 5

Step-by-step explanation:

It usually works to follow directions.

a) Substitute the numbers into the formula:

v = u + at

49 = 0 +9.8t

b) Solve the equation:

49/9.8 = t = 5 . . . . . divide by the coefficient of t

You want to make a rectangular banner that is 18ft. Long with a trim around the entire border of the banner . You have no more t

lys-0071 [83]

Answer:

6 ft

Step-by-step explanation:

Given that:

Length of rectangular banner = 18 ft

Total trim of banner available = 48 ft

To find:

Possible widths of the banner = ?

Solution:

Maximum trim available of the banner around the entire border of the banner = 48 ft

i.e. we are given the total perimeter of the rectangular banner.

Formula for perimeter of a rectangle is given as:

$Perimeter = 2 \times (Length + Width)$

Putting the values of perimeter and length to find the value of width.

$48 = 2 \times (18 + Width)\\\Rightarrow 48 =36+2 \times Width\\\Rightarrow 2 \times Width = 48-36\\\Rightarrow 2 \times Width = 12\\\Rightarrow \bold{Width = 6\ ft}$

So, width possible is 6ft.

Jennifer earns $17.35 per hour at her job. She works 6 hours per day, 5 days per week. What is Jennifer’s gross income for a 2 w

Marat540 [252]

Answer:

She makes $1041 in 2 weeks

Step-by-step explanation:

First, we can work on finding how much she makes in a day. To find the daily income, we need to multiply 17.35 by 6 since she works 6 hours a day.

17.35x6=104.1

She makes $104.10 a day. Now we multiply by 5 since she works 5 days a week

104.10x5=520.50 a week

Since we are trying to find how much she makes in two weeks, we multiply the weekly income by 2

520.5x2=1041

She makes $1041 in 2 weeks
