Question

A 20 kg object is pushed with a net force of 60 N. What is the acceleration of the object?

A) 0.33 m/s²
B) 3 m/s²
C) 30 m/s²
D) 1200 m/s²

Answer 1

To find the acceleration of an object when a net force is applied, you can use Newton's second law of motion, which states:

\[
F = ma
\]

where:
- \( F \) is the net force applied to the object,
- \( m \) is the mass of the object, and
- \( a \) is the acceleration of the object.

Rearranging the formula to solve for acceleration \( a \) gives us:

\[
a = \frac{F}{m}
\]

In this case:
- The net force \( F = 60 \) N,
- The mass \( m = 20 \) kg.

Plugging in the values:

\[
a = \frac{60 \, \text{N}}{20 \, \text{kg}} = 3 \, \text{m/s}^2
\]

So, the acceleration of the object is \( 3 \, \text{m/s}^2 \).

The correct answer is **B) 3 m/s²**.
