Question

The force an object exerts can be found using the formula F = ma, where F is the force, m is the mass of the object, and a is the object's acceleration.

If an object with an acceleration of 2.3 m/s2 exerts a force of 9.2 kg·m/s2, what is the mass of the object?
6.9 kg
1.7 kg
4 kg
21.16 kg

Answer 1

would it be 1.7 kg

Answer 2

This is Newton's second law. Just plug in the values into the formula given to you.

Force = 9.2 kg m/s^2 (kilogram meters per second squared)
Acceleration = 2.3 m/s^2 (meters per second squared)

\[F = ma\]
\[9.2 = m(2.3) \implies 9.2\div2.3=mass\]

Answer 3

@DCANBCA
You are incorrect.

Answer 4

wow my teacher is wrong

Answer 5

he told me that was the answer

Answer 6

Did he show how he got the mass?

Answer 7

no he done it with a pen and paper and told that was the answer

Answer 8

Well I don't see how that works...
\[9.2 \div 2.3 =4kg\]
Not 1.7kg...

Answer 9

well he is a math teacher

Answer 10

so idk

Answer 11

4kg is right

Answer 12

cool beans Opcode

Answer 13

well thanx u to alot for all your help

Answer 14

No problem :-).
