Motion problem when acceleration is constant

Click For Summary
SUMMARY

The discussion focuses on a physics problem involving a coin dropped from an elevated position, experiencing a constant acceleration of 10 m/s². Key calculations include determining the coin's velocity after 2 and 5 seconds, the distance fallen in those time frames, and the time taken to fall specific distances of 5m and 10m. Additionally, the problem compares the coin's motion with that of a feather, which falls with an acceleration of 3.0 m/s² due to air resistance. The relevant equations for uniformly accelerated motion are essential for solving these problems.

PREREQUISITES
  • Understanding of kinematic equations for uniformly accelerated motion
  • Knowledge of acceleration, velocity, and distance relationships
  • Familiarity with basic physics concepts such as free fall
  • Ability to apply mathematical calculations in physics contexts
NEXT STEPS
  • Study the kinematic equations: \( v = u + at \) and \( s = ut + \frac{1}{2}at^2 \)
  • Learn how to calculate time of flight for objects under constant acceleration
  • Explore the effects of air resistance on falling objects
  • Practice solving problems involving multiple objects with different accelerations
USEFUL FOR

High school students studying physics, educators teaching kinematics, and anyone interested in understanding the principles of motion under constant acceleration.

Homework Statement


A coin, initially at rest is dropped from an elevated position and freely falls to the ground with an acceleration of 10m/s/s.
a) How fast is the coin traveling after 2 sec b) How fast is the coin traveling after 5 seconds
c) How far does the coin fall after 2 sec d) How far does the coin fall after 5 sec
e) How much time does it take the coin to fall 5m f) How much time does it take the coin to fall 10m g) What is the velocity of the coin after it has fallen 5 m h) What is the velocity of the coin after it has traveled 10m i) A feather is dropped at the same time as the coin and falls with an acceleration of 3.0 m/s/s (due to air resistance). What is the speed of the feather after the coin has fallen 5m

I don't know


The Attempt at a Solution


I am terrible at physics and have absolutely no idea what to do. I don't even know where to start. I am a high school student in college physiscs...so yeah.
