WebFeb 19, 2004 · Remember that velocities are vectors, so use vector addition. The final velocity should be zero, if you go to large t, as the friction will bring the disk to a stop. To find the final displacement, integrate the velocity with respect to time. I hope this helps you, and that I haven't taken too long to get back to you. Webinitial velocity (u) is measured in metres per second (m/s) acceleration (α) is measured in metres per second squared (m/s²) displacement (x) is measured in metres (m) …
Initial Velocity Formula - Softschools.com
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. WebYou are trying to find the final velocity v. u = 0 ms − 1 is the initial velocity, a = − g ms − 2 and s = 3.70 m. Then, you can find the time taken using v = u + a t, by using the velocity you found on the first part.

WebFeb 19, 2024 · In this case, we can rearrange the equation and solve like this: speed = distance/time. speed × time = (distance/time) × time. speed × time = distance. 20 km/h × 4 h = distance = 80 kilometers. 2. Convert your units as needed. Sometimes, you may calculate speed in one set of units but need it in another. WebJan 16, 2024 · a =. v ( f) − v ( i) t ( f) − t ( i) In this acceleration equation, v ( f) is the final velocity while is the v ( i) initial velocity. T ( f) is the final time and t ( i) is the initial time. Some other things to keep in mind when using the acceleration equation: You need to subtract the initial velocity from the final velocity. WebFormula for velocity as a function of initial velocity, acceleration and time v = u + at u = initial velocity v = final velocity a = acceleration t = time Example: Find time (t) given final velocity (v), initial velocity (u) and … dictionary for a better world
