WebThe original answer apparently assumed that the velocity you knew was only the initial one. In that case that answer is correct as stands. You seem to assume we know both the initial and final velocities. In that case we know the average velocity (if the acceleration is constant) v ave = (v F +v I)/2 and can then solve for t=d/v ave. WebIf the starting time t0 is taken to be zero, then the average velocity is simply \displaystyle \bar {v}=\frac {\Delta x} {t} v¯ = tΔx. Notice that this definition indicates that velocity is a vector because displacement is a vector. It has both magnitude and direction.

How do you find final velocity in momentum? [Fact Checked!]

WebFeb 14, 2024 · Here, since you need to determine the velocity in meters per second, first convert time to seconds: (1.5 hours) (60 minutes) (60 seconds) = 5,400 seconds (1.5hours)(60minutes)(60seconds) = 5,400seconds Then, plug your known variables into the velocity formula: V = \dfrac {\bigtriangleup x} {t} V = t x WebJan 16, 2024 · You need to subtract the initial velocity from the final velocity. If you reverse them, you will get the direction of your acceleration wrong. If you don’t have a starting time, you can use “0”. If the final velocity is less than the initial velocity, the acceleration will be negative, meaning that the object slowed down. shantiapartments praia da rocha
