Question

A particle that has a mass of 5.0 kg is acted on by a force of 4.5 N. The acceleration of the particle is: a 0.9 m/s^2 b 1.1 m/s^2 c. 2.9 m/s^2 d. 22.5 m/s^2

Answer 1

a)
`a = 0.9 m/s^2`

Step-by-step explanation:

As per Newton's 2nd law we know that net force on an object of mass "m" is given by the formula

`F = ma`

so net force is the product of mass and acceleration

here we know that

mass = 5 kg

net force on the particle is 4.5 N

so from above equation we have

`4.5 = 5 * a`

so the acceleration is given as

`a = (4.5)/(5) = 0.9 m/s^2`
