Question

On a 3 kg mass 5 N of force acts for 0.1 second the impulse imparted to mass is (in kg m/s))

Answer 1

Answer:

given

force=5N

and mass 3kg and time =0.1

now force=mass× acceleration. 5=3×a

and a=5/3 impulse force is also a kind of force. now F=m×a this implies 3×5/3 the impulse force is 5kgm/s

Answer 2

The impulse imparted to the mass is 0.5 kg-m/s.

Explanation:

It is given that,

Mass of the object, m = 3 kg

Force acting on the object, F = 5 N

Time of contact, t = 0.1 s

Let J is the impulse imparted to mass. It is equal to the product of force and time of contact. It is given by :

$J=F\times t$

$J=5\ N\times 0.1\ s$

J = 0.5 kg-m/s

So, the impulse imparted to the mass is 0.5 kg-m/s. Hence, this is the required solution.
