Correct answer is C
According to Newton's second law of motion, \(force = \frac{ final momentum - initial momentum}{time}\)
but momentum = mass x velocity; F= 5N, Initial mass = 5kg, time = 5secs, initial velocity = zero
then final momentum = force x time (since initial momentum of the mass = 0, that is 5 x 0)
= 5 x 5 = 25 kgms-1
