A 75 Kg skateboarder is riding downhill, exerting 25 N. What is their acceleration?
Hunter-Best [27]

Answer:

<h3>The answer is 0.33 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

where

m is the mass

f is the force

a is the acceleration

From the question

f = 25 N

m = 75 kg

We have

a =  \frac{25}{75}   =  \frac{1}{3}  \\  = 0.333333333...

We have the final answer as

<h3>0.33 m/s²</h3>

Hope this helps you
