How do you find velocity with time and mass?
Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time. Displacement = velocity × time.
How do you find velocity with mass?
Subtract the object’s initial speed from its final speed. If, for instance, it accelerates from 20 m/s to 50 m/s: 50 – 20 = 30 m/s. Divide this answer by the time it spends accelerating. For instance, if the object accelerates over the course of 5 seconds: 30 ÷ 5 = 6 m/s².

Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time.
Does mass affect how fast an object falls?
Both objects fall at the same speed. Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time.
