A body of mass 200 gm lies on a rough surface whose coefficent of friction are mus = 0.5 and muk = 0.3. A horizontal force F varies as F = t/2 (where F in newton and t in sec ) is applied on body. Calculate -: (g = 10m/s )
  1. accleration at time t = 1s, 2s, 3s.
  2. velocity at time t = 3s.

Dear adityagupta9696@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

We have not understood the query that you have posted.
You have mentioned that F varies as F = t/2. This equation is dimensionally incorrect as L.H.S is in newtons and R,H.S is in seconds.
Kindly check the quation and post it again so that we may answer this to the best of the ability.
