Homework: Acceleration of a rocket along a track

Click For Summary
SUMMARY

The discussion centers on calculating the acceleration of a rocket-driven sled, specifically the Sonic Wind No. 2, which accelerates from rest to a speed of 224 m/s over a duration of 0.900 seconds along a 1070 m track. The correct formula for acceleration, given constant acceleration, is a = Δv / Δt, where Δv is the change in velocity and Δt is the change in time. Participants confirmed that the initial velocity (V) is 0 m/s, the final velocity (Vf) is 224 m/s, and the time (t) is 0.900 seconds, leading to a calculated acceleration of approximately 248.89 m/s².

Homework Statement



th rocket driven sled sonic wind no. 2 used for investigating the physiological effects of large accelerations, runs on a straight, level track 1070m long. Starting from rest. it can reach a speed of 224m/s in 0.900s

compute for its acceleration assuming that it is constant

Homework Equations


im confused which equations do i have to use
is it
Vf=V+at
Vf2]=V2+2ax or
x=Vt+1/2at2

my v=0, Vf=224m/s, t=.900s, x=1070
is this correct?

Even more simple than that. What is acceleration? It's the rate of change of velocity with respect to time. So, mathematically:

[tex]a=\frac{\Delta v}{\Delta t}[/tex]

So, average acceleration is the change in velcity divided by the change in time (which is just another way of writing the first equation you wrote)
