The formula for calculating velocity at Point 2 is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
The initial velocity can be determined by using the formula v = u + at. Rearrange the formula to solve for u: u = v - at. Plug in the known values for v, a, and t to calculate the initial velocity.
Yes, this formula can be used for any type of motion where there is a constant acceleration. However, if the acceleration is not constant, a different formula may need to be used.
The units used should be consistent throughout the formula. Common units for velocity are meters per second (m/s) and for time are seconds (s). Acceleration can be measured in meters per second squared (m/s^2).
Yes, you can check your calculation by using the formula v^2 = u^2 + 2as, where s is the displacement. Plug in the calculated values for u, a, and s to see if the final velocity matches the value you calculated initially.
