The four balls have different masses and speeds.
ball a: mass of 0.7 kg, speed of 15.0 m/s.
ball b: mass of 1.2 kg, speed of 5.5 m/s.
ball c: mass of 2.5 kg, speed of 5.0 m/s.
ball d: mass of 5.0 kg, speed of 1.5 m/s.
rank them in terms of momentum, from greatest to least.

the balls in the image above have different masses and speeds. rank them in terms of momentum, from greatest to least.

c, a, d, b
a, b, c, d
d, c, b, a
b, d, a, c

The balls whose velocity and mass is given and momentum of the balls are ranked as C, A, D, B from greatest to least.

Momentum is the quantity of physics. Momentum is the product of mass and velocity of the object. Rate of change in momentum is called as force, change in momentum is called impulse. The units of momentum is kg.m/s  

Momentum is represented as P which is given by the formula:

Now to calculate the momentums of balls in which speed and mass was given,

Take Ball A:

Mass = = 0.7 kg, Speed = = 15.0 m/s

Momentum = 0.7 15.0

Therefore,

= 10.5 kg.m/s

Momentum of ball A is 10.5 kg.m/s

Take Ball B:

Mass = = 1.2 kg, Speed = = 5.5 m/s

Momentum = 1.2 \times 5.5

Therefore,

= 6.6 kg.m/s

Momentum of ball B is 6.6 kg.m/s

Take Ball C:

Mass = = 2.5 kg, Speed = = 5.0 m/s.  

Momentum = 2.5 \times 5

Therefore,

= 12.5 kg.m/s

Momentum of ball C is 12.5 kg.m/s

Take Ball D:

Mass = = 5.0 kg, Speed = = 1.5 m/s.

Momentum = 5.0 1.5

Therefore,

= 7.5 kg.m/s

Momentum of ball D is 7.5 kg.m/s

On comparing the values of momentum,

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
