Question

a force of 10n accelerates on a object from 15m/s to 25m/s in 20sec. calculate the mass of the object.

Answer 1

Acceleration = Final Velocity - Initial velocity / Time
 = 25 - 15 / 20 = 10/20 = 0.5 m/s^2

Force = Mass * Acceleration
Mass = Force / Acceleration
= 10 N / 0.5 m/s^2
= 20 kg.


Therefore,
Mass = 20 kg.
