Answer:

D. 15 kgm/s is the value of impulse applied

. Greetings !

Given values

  • mass(m) =4kg
  • initial velocity (u) =2 m/s
  • Force(F) =5N
  • Time (t) =3 sec

required value

  • Impulse = ?

Solution :

  • [tex]impulse = force \times  Δtime \\ impulse = (5) \times (3)...substitute \: values \\ impulse = 15kgm/s[/tex]
