find two consecutive integers such that ten more than twice the smaller is seven less than three times the larger

Radda [10]

This is how I would work it out:

1st no. = x+1 2x+10=3(x+1)-7
2nd no. = x 2x+10=3x-4
x=14

1st no. is 15; 2nd no. is 14

To check: 28+10=38; three times the larger is 45; and 38 is 7 less than 45.

An 8.0 kg block is moving at 3.2 m/s. A net force of 10 N is constantly applied on the block in the direction of its movement, u

Softa [21]

Answer:

5.02 m/s

Step-by-step explanation:

We are given that

Mass of block,m=8 kg

Initial velocity,u=3.2 m/s

Net force ,F=10 N

Distance,s=6 m

We have to find the approximate final velocity of the block.

We know that $a=\frac{F}{m}$

Using the formula

$a=\frac{10}{8}=\frac{5}{4} m/s^2$

We know that

$v=\sqrt{u^2+2as}$

Using the formula

$v=\sqrt{(3.2)^2+2\times \frac{5}{4}\times 6}$

$v=5.02 m/s$
