SUMMARY

The discussion centers on calculating the speed at which the stern of the passenger liner France passes a pier while the ship accelerates uniformly. Given the ship's length of 315.5 meters and an initial speed of 2.5 m/s with an acceleration of 0.01 m/s², the calculated speed of the stern when it passes the pier is 3.42 m/s. The solution involves using kinematic equations that account for acceleration, specifically the formula a = (v - u) / (T - t).

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Familiarity with concepts of acceleration and uniform motion
  • Knowledge of basic algebra for solving equations
  • Ability to manipulate formulas involving time, speed, and distance
NEXT STEPS
  • Study kinematic equations in detail, focusing on acceleration scenarios
  • Learn about the derivation and application of the formula a = (v - u) / (T - t)
  • Explore real-world applications of motion equations in engineering contexts
  • Practice problems involving uniformly accelerated motion to reinforce understanding
USEFUL FOR

Students in physics or engineering courses, educators teaching motion concepts, and anyone interested in applying kinematic equations to real-world scenarios.

Homework Statement



The longest passanger liner ever built was the Fracnce, at 66,348 tons and 315.5m long.
Suppose its bow passes the edge of a pier at a speed of 2.5m/s while the ship is accelerating uniformly at 0.01m/s^2. At what speed will the stern of the ship pass the pier?


Homework Equations



um... i think, a= (v-u) / (T-t)


The Attempt at a Solution



0.01 = (v-2.5) / ((315.5/v)-0)
v= 3.42 m/s
 
Physics news on Phys.org
The final time won't be 315.5/v since x=vt is only true when there is no acceleration. Since it is accelerating you will have to look through your list of formulas that include acceleration.

Since you know x-x_0, v_0, and a. There is one particular formula that is very useful.
