Answer:

49

Step-by-step explanation:

<h2><u>Lesson : Reducing by factors:</u></h2><h2><u /></h2>

Given :

196ft^2

Reduced * factor * of * \frac{1}{4}

When you have to reduce a number by a certain factor, you must divide the area with the amount that it is reducing from, therefore,

\frac{196}{4}

The distance travelled is 10 m

The velocity gained at the end of the time is 2 m/s

<h3>Motion</h3>

From the question, we are to determine distance travelled and the velocity gained

From one of the equations of motion for <u>linear motion</u>, we have that

S = ut + 1/2at²

Where S is the distance

u is the initial velocity

t is the time taken

and a is the acceleration

First, we will calculate the acceleration

Using the formula,

F = ma

Where F is the force

m is the mass

and a is the acceleration

∴ a = F/m

Where F is the force

and a is the acceleration

From the given information,

F = 50 N

m = 250 kg

Putting the parameters into the equation,

a =  50/250

a = 0.2 m/s²

Thus,

From the information,

u = 0 m/s (Since the object was initially at rest)

t = 10 s

S = 0(t) + 1/2(0.2)(10)²

S = 10 m

Hence, the distance travelled is 10 m

For the velocity

Using the formula,

v = u + at

Where v is the velocity

v = 0 + 0.2×10

v = 2 m/s

Hence, the velocity gained at the end of the time is 2 m/s

One positive number is 9 more than twice another. If their product is 731 find the numbers
Anastaziya [24]
The answer is 361.

This is because you take 731 and subtract 9 and you get 722. Then you divide 722 by two and you get 361.

Hope this helped!!
