Question

Two objects A and B, having mass 500 kg and 250 kg, moving

with velocity 50 km/hr and 40 km/hr respectively. Answer the

following:

i.Which will have greater inertia?

ii.Which will have greater momentum?​

Answer 1

Answer:

(i) Object A

(ii) object A

Explanation:

inertia is determined by the mass.

greater mass implies that greater inertia.

so, mass of A > mass of B

hence, inertia of A > inertia of B

now,

momentum of A = mass×velocity

= 500×50

= 25000 kg km/h

momentum of B = mass×velocity

= 250×40

= 10000 kg km/h

so, momentum of A > momentum of B

Answer 2

Answer:

i) Object A will be having more inertia because more the mass and is equal to greater inertia

ii) Object A's momentum = p = mv = 500*50 =25000 kg m/s

Object B's momentum =250*40 = 10000 kg m/s
