Question

A constant force of 10 N acts on a 2.5 kg object for 9 seconds. What is the velocity of the object?

Answer 1

`\huge\boxed{\sf v = 36 \ m/s}`

Step-by-step explanation:

Given data:

Force = F = 10 N

Mass = m = 2.5 kg

Time = t = ?

Required:

Velocity = v = ?

Formula:

`\displaystyle F=(mv)/(t)`

Solution:

Put the given data in the above formula.

`\displaystyle 10=((2.5)v)/(9) \\\\10 * 9 = 2.5v\\\\90=2.5 v\\\\Divide \ 2.5 \ to \ both \ sides\\\\90/2.5=v\\\\36 \ m/s=v\\\\v = 36 \ m/s\\\\\rule[225]{225}{2}`
