Question

Which of the following has greater momentum?
a. An object of mass 2 kg moving with uniform velocity of 2 ms⁻¹.
b. An object of 1kg mass moving with uniform velocity of 3 ms⁻¹.

Answer 1

momentum, p = m * v
In a, p= 2*2=4 kgm /s
In b, P=1*3= 3 kgm/s
So, the ans is a

Answer 2

Dear student,

◆ Answer -

First(a) object has greater momentum than second(b) object.

● Explanation -

(a) An object of mass 2 kg moving with uniform velocity of 2 ms⁻¹ -

Linear momentum of first object is given by -

P1 = m1 × v1

P1 = 2 × 2

P1 = 4 kgm/s

(b) An object of 1kg mass moving with uniform velocity of 3 ms⁻¹ -

Linear momentum of second object is given by -

P2 = m2 × v2

P2 = 1 × 3

P2 = 3 kgm/s

As P1 > P2, first(a) object has greater momentum than second(b) object.

Hope this helps you...
