A 10n force acting on a certain mass increases its speed uniformly from 0 to 25 m/s in 5s. The magnitude of the mass in kg is?

Expert's answer

The acceleration of an object

"a=\\frac{\\Delta v}{\\Delta t}=\\frac{25}{5}=5\\:\\rm m\/s^2."The mass of an object

"m=\\frac{F}{a}=\\frac{10}{5}=2\\:\\rm kg."
