Question

A roller coaster pushes a 27 kg person upward with a force of 432 N. What is the acceleration?

Answer 1

Given:

• Mass of person, m = 27 kg

,

• Force = 432 N

Let's find the acceleration.

To find the acceleration, apply Newton's Second Law:

`F=m*a`

Where:

F is the Force

m is the mass

a is the acceleration.

Rewrite the formula for a, plug in the values of m and F, the solve:

`\begin{gathered} a=(F)/(m) \\ \\ a=\frac{432\text{ N}}{27\text{ kg}} \\ \\ a=16\text{ m/s}^2 \end{gathered}`

Therefore, the acceleration is 16 m/s².

ANSWER:

16 m/s²
