Question

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

Answer 1

Answer: 0.5 kgm/s

Explanation:

Mass = 3 kg

Force = 5N

Time = 0.1 s

Force  = ma

5 = 3 * a

5/3 = a

Initial velocity(u) = 0 m/s

Acceleration = (v - u)/t

5/3 = (v - 0)/0.1

5/3 * 0.1 = v

Therefore, v = 0.5/3 m/s

Initial momentum =  3 * 0 = 0 kgm/s

Final momentum = 0.5/3 * 3 = 0.5 kgm/s

Impulse = mu - mv

Therefore Impulse = 0.5 kgm/s
