3 Ways to Calculate Velocity - wikiHow
The velocity at 30cm from the end (your fastest, hopefully) will be our final velocity for every calculation. To find the acceleration between 40cm and 30 cm, just subtract your 40cm velocity from the 30cm velocity and divide by the time difference. You can fill in the data on the lab report.

You need to find the component of velocity in the easterly direction. From the end of the velocity arrow, draw a line straight line down to the x-axis, point A. Measure from the origin O to A. Convert this distance using the scale into m s–1: length of line = 6.9 divisions . component of velocity towards the east = 3.45 m s–1

Use the conservation of angular momentum to find the final angular velocity . f. of the wheel. Doctor evil wasn’t paying attention during his college physics relativity lectures, so he didn’t hear about how you can’t accelerate an object with mass to a speed faster than the speed of light. Comment on the tangential velocity of the wheel ...

Instantaneous Velocity. Zero. 2.3h. 11 km. Speed. A position time graph is more useful, as you can find the direction (position) of the person or object over a period of time. The object is travelling away from the starting position and is travelling with an increasing velocity (the object is speeding up, or accelerating).

Find the final velocity if a mass m1 moving at velocity v1 collides inelastically with a mass m2 moving at velocity v2. Since they stick together, we apply momentum conservation: m1v1 + m2v2 = (m1 + m2) v’ and solving for v’ is simple algebra.
