Resource summary

Question 1

Question
The acceleration, a of an object is given by: a=vfvit where vf is the final velocity, vi is the initial velocity, and t is the time interval.  Rearrange this equation to make vi the subject.
Answer
  • vi=atvf
  • vi=a+tv
  • vi=a+t+vf
  • vi=atvf
  • vi=vfat

Question 2

Question
E=mgh+12mv2 Rearrange this equation for v
Answer
  • v=2(Emgh)
  • v=12(Emgh)
  • v=2(Emgh)
  • v=2m(Egh)
  • v=m2(Egh)

Question 3

Question
If ω=2πT, and k=mω2, what is T in terms of m and k?
Answer
  • T=2πmk
  • T=2πmk
  • T=2πkm
  • T=2πkm
  • T=4π2mk

Question 4

Question
P2=ρgh+P1 and Q=πR4(P2P1)8ηL.Eliminate P1 and P2 and write an equation for h in terms of Q, R, ρ, g, η and L.
Answer
  • h=8ηLQπR4ρg
  • h=8ηLQπR4ρg
  • h=8ηLQπR4πR4ρg
  • h=8ηLQπR4ρg
  • h=πR48ηLQρg

Question 5

Question
Rearrange: σρ=ml3(σmm)2+3(σll)2
for σm
Answer
  • σm=m(σρl3m)23(σll)2
  • σm=m(σρl3m)2+3(σll)2
  • σm=ml3(σρl3m)23(σll)2
  • σm=m((σρl3m)23(σll)2)
