For a more difficult training session, the mass to be pushed is increased to 160 kg. If the players still push with a force of 1

leva [86]

As you already written, you have to use Newton's law

$F=ma$

where F is the force, m is the mass, and a is the acceleration.

You already know the mass and the force, so you have to solve the equality for the acceleration:

$a = \dfrac{F}{m}$

plug the given values:

$a = \dfrac{150}{160} = \dfrac{15}{16} = 0.9375$

Write an equation rectangular room 3 meters longer than it is wide and its perimeter is 18 meters

Anon25 [30]

width = x

length = 3 + x

perimeter = x + x + ( 3 + x ) + (3+x)

18 = x + x + ( 3 + x ) + (3+x)

x + x + ( 3 + x ) + (3+x) = 18

6 + 4x = 18

4x = 12

x = 3

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 3)

Point (2, -6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-6-3}{2-2}$
Subtract: $m=\frac{-9}{0}$
Define: m = undef
