Answer:

(a)

Explanation:

We are required to find out the force.

We know that
Force #F=ma#.
Mass #m# is given.
What we need to find is acceleration #a# from the given data.

Kinematic equation connecting given quantities is
#s=ut+1/2at^2#
Inserting given values we get
#s=0xxt+1/2at^2#
#=>1/2at^2=s#
Solving for #a#
#a=(2s)/t^2#
#:.# Force #F=mxx(2s)/t^2#
#F=(2ms)/t^2N#
