Answer:
0.02
Explanation:
Force,
where N is normal reaction and coefficient of kinetic friction is
. Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making
the subject of the formula then

Substituting F with 2 N, m with 10 kg and g with 9.81 then

P = m v
250 = m5
250 = 5m
m = 50 Kg
