Question

the linear momentum P of a body varies with time is given by the equation P=x+yt^2 where x and you are constant . the net force acting on the body for one directional motion is proportional to :
a)t^2
b)A constant
c)t
d)1/t
sorry it's of chemistry

Answer 1

force= dp/dpt
= x + 2yt
so proportional to t
