Question

1. The relation between the displacement x and
the time t of a particle moving under a constant force is
t = x + 3, where x is in metre and t in sec. Determine :
(i) the displacement of the particle at that instant when
its velocity is zero, (ii) the work done by the force in
first 6 seconds.​

Answer 1

Answer:

Here is this the answer :

Explanation:

1) If velocity is zero, the displacement is zero as,

  m/s = 0

  so, m = 0

2) Work done = Force * displacement

   if Force is F (constant)

   then, Work done = F * (displacement2 - displacement1)

   or, Work done = F *  3-(-3)

   or, Work done = F * 6

   or, Work done = 6F

Hope this helps.
