Dmitry [639]

Answer:

2.5\ m/s^2

Step-by-step explanation:

Newton's Second Law: Force on a body is equal to the product of mass and acceleration of the centre of the mass of the body.

Force(F)=Mass(m)\times Acceleration(a)

Initially:

Let\ mass=m\ kg\\\\acceleration=10\ m/s^2\\\\Force(F)=m\times 10=10m

At the end of the road:

Let\ mass=4\times m\ kg\\\\acceleration=a\ m/s^2\\\\Force(F)=4m\times a=4ma

Both\ forces\ are\ equal\\\\4ma=10m\\\\divide\ both\ the\ sides\ by\ m\\\\4a=10\\\\a=\frac{10}{4}\\\\a=2.5\ m/s^2

explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction
Tomtit [17]
Think:  You're treating the numerator and the denom. in precisely the same way.  In doing so you are NOT changing the value of the fraction, only the appearance.

Example:  start with 2/3.  Mult num. and den. both by 7:  14/21.

2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.

A snail travels 1/8 mile in 3/4 hour. The snail's speed is miles per hour.
Vera_Pavlovna [14]

9514 1404 393

Answer:

  1/6 mph

Step-by-step explanation:

To find miles per hour, divide miles by hours.

  (1/8 mi)/(3/4 h) = (1/8×4/3) mi/h = 1/6 mi/h

The snail's speed is 1/6 miles per hour.

What is sin B? <br> 15/17 <br> 8/17 <br> 12/17 <br> Not enough information
Fittoniya [83]

SinB = 8/17

The sin of an angle is equal to opposite/hypotenuse

Use Pythagorean’s Theorem to solve for the opposite side

15^{2} +b^{2}=17^{2}  \\225 + b^{2} =289\\b^{2} =64\\b=8

The opposite side is equal to 8

So sinB = 8/17
