Velocity of approach Solution

Follow our step by step solution on how to calculate Velocity of approach?

FIRST Step Consider the formula

v app = \frac{v 2 - v 1}{e}

Next Step Substitute values of Variables

∴

v app = \frac{20m/s - 16m/s}{0.5}

Next Step Prepare to Evaluate

∴

v app = \frac{20 - 16}{0.5}

LAST Step Evaluate

∴

v app = 8m/s

How to Evaluate Velocity of approach?

Velocity of approach evaluator uses Velocity of Approach = (Final Velocity of Second Mass-Final Velocity of First Mass)/(Coefficient of Restitution) to evaluate the Velocity of Approach, The Velocity of approach formula is defined as the ratio of difference of final velocity of second body and final velocity of first body to the coefficient of restitution. Velocity of Approach is denoted by v_app symbol.

How to evaluate Velocity of approach using this online evaluator? To use this online evaluator for Velocity of approach, enter Final Velocity of Second Mass (v₂), Final Velocity of First Mass (v₁) & Coefficient of Restitution (e) and hit the calculate button.

FAQs on Velocity of approach

What is the formula to find Velocity of approach?

The formula of Velocity of approach is expressed as Velocity of Approach = (Final Velocity of Second Mass-Final Velocity of First Mass)/(Coefficient of Restitution). Here is an example- 8 = (20-16)/(0.5).

How to calculate Velocity of approach?

With Final Velocity of Second Mass (v₂), Final Velocity of First Mass (v₁) & Coefficient of Restitution (e) we can find Velocity of approach using the formula - Velocity of Approach = (Final Velocity of Second Mass-Final Velocity of First Mass)/(Coefficient of Restitution).

What are the other ways to Calculate Velocity of Approach?

Here are the different ways to Calculate Velocity of Approach-

Velocity of Approach=Initial Velocity of Mass*cos(Angle between Initial Velocity and Line of Impact)

Can the Velocity of approach be negative?

No, the Velocity of approach, measured in Speed cannot be negative.

Which unit is used to measure Velocity of approach?

Velocity of approach is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Velocity of approach can be measured.
