Kinematics: Constant Acceleration

Click For Summary
SUMMARY

The discussion focuses on calculating the final velocity of a badminton shuttle experiencing constant acceleration. The initial horizontal velocity is 73 m/s [W], and the air resistance causes a constant acceleration of 18 m/s² [E]. Using the formula V2 = V1 + at, the final velocity after 1.6 seconds is determined to be 44 m/s [W]. Participants emphasize the importance of ensuring unit consistency and clarity in calculations for accurate results.

PREREQUISITES
  • Understanding of kinematic equations, specifically V2 = V1 + at
  • Knowledge of vector components in physics
  • Familiarity with units of measurement in physics (m/s, m/s²)
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Review kinematic equations for motion with constant acceleration
  • Study vector addition and its application in physics problems
  • Practice solving problems involving air resistance and its effects on motion
  • Explore real-world applications of kinematics in sports physics
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of kinematics and motion analysis in sports contexts.

A badminton shuttle, or "birdie" is struck, giving it a horizontal velocity of 73m/s [W]. Air resistance causes a constant acceleration of 18m/s^2 [E]. Determine its velocity after 1.6s.

I've used the equation V2=V1+ax x t

V2= Final velocity
V1=initial velocity
A= Acceleration
t=time

The answer should be 44m/s [W] But I don't know how they got that. HELP PLEASE! :)

Hmm, not sure about the equation you've given with the many "x" variables, although if you mean V2 = V1 + at then that's fine. Where the last term is acceleration multiplied by time.

What is the answer you got? Do a sanity check i.e. do your units match, does your answer even make sense in the first place? Can't help you with a problem if you don't show what the problem you're having is :)
 
Maybe you show us your calculation.
