Calculate the force created from an object with a mass of 1250 grams and an acceleration of 3 m/s^2

abruzzese [7]

The force created by the object is 3.75 Newton.

Given

Mass of the object (m) = 1250 grams

Convert 1250 grams to kilograms by dividing it by 1000.

Mass (m) = 1.25 kg

Acceleration of the body (a) = 3 $m/s^{2}$

From Newton's second law we know $F= m *a$

By Substituting in the above equation we get

Force = 1.25 x 3

Force = 3.75 $kg/m /s^{2}$

It can also be written as force = 3.75 N

Hence Force created by the body is 3.75 Newton.

Please help! posted picture of question

o-na [289]

C. 5x - 2y = 16 is your answer

plug in each point into the equation.

(2, -3)

x = 2, y = -3

5(2) - 2(-3) = 16
10 + 6 = 16
16 = 16 (True)

(4,2)

x = 4, y = 2

5(4) - 2(2) = 16
20 - 4 = 16
16 = 16 (True)

hope this helps
