Answer:
.
Step-by-step explanation:
We know that According to Newton's Second Law that :
Force acting on an object is equal to the Mass of that Object multiplied by the Acceleration of that Object.
Given Mass of the Car as : 2000 kg
Acceleration of the Car as : 2 m/s²
Force required to move the Car = 2000 × 2 = 4000 Newton
Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11
