A particle of mass m is acted upon by a force F given by the empirical law F=Rt2 vt. If this law is to be tested experimentally by observing the motion starting from rest, the best way is to plot
  1. logvt against1t
  2. vt against t2
  3. logvt against1t2
  4. logvt against t

Solution

F=Rt2vtmdvdt=Rt2vt

dvv=Rdtmt2

ln v=-Rmt

  ln v1t
