C

First we need to calculate the acceleration #a# of snail.

Using the following kinematic expression

#v=u+at# ..........(1)
where #v# is the final velocity after time #t# and #u# is the initial velocity.

Inserting given vales we get
#0.01=0+axx5#
#=>a=0.01/5=0.002" ms"^-2#

Now using the following expression to calculate force

#F=ma#

we get
#F=0.05xx0.002=0.0001=10^-4" N"#
