Question

Darius runs with an acceleration of 21 m/s2 and has a force of 400N. Calculate his mass.

Answer 1

we can use the formula

`F=m* a`

where F is the force, m the mass and a the acceleration

now, replacing

`400=m*21`

then solve for m

`\begin{gathered} m=(400)/(21) \\ \\ m=19.05 \end{gathered}`

the mass is 19.05Kg
