An object has a mass of 13.5 kilograms. what force is required to accelerate it to a rate of 9.5 m/s2? a. 128.25 n b. 173.75 n c. 81.00 n d. 132.30 n

Option A is correct

The force is required is  128.25 N

Step-by-step explanation:

Given: mass of an object (m) = 13.5 kilogram and acceleration (a) = 9.5

To find the force required;

According to Newton's second Law:

Net Force= mass times acceleration i.e F = ma

Using second law, and substitute the given values above we have;

We know that 1 Newton =

therefore; the force is required is, 128.25 N

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

pi x^2

step-by-step explanation:

pi times x squared
