Two objects of same material are travelling
near you. Object A is a 1.9 kg mass traveling
8.3 m/s; object B is a 2 kg mass traveling
5 m/s.
Which object would make you feel worse if
you are hit by it?
It is a subjective question. Some folks like to be hit by large objects.
The greater momentum is in which object?
momentum= mass*velocity
To determine which object would make you feel worse if you are hit by it, we need to consider the concept of momentum.
Momentum is a physical quantity that depends on both the mass and velocity of an object. The formula for momentum is:
momentum = mass x velocity
So, to calculate the momentum of object A, we can use the given values:
mass of object A = 1.9 kg
velocity of object A = 8.3 m/s
momentum of A = 1.9 kg x 8.3 m/s = 15.77 kg·m/s
To calculate the momentum of object B, we can use the given values:
mass of object B = 2 kg
velocity of object B = 5 m/s
momentum of B = 2 kg x 5 m/s = 10 kg·m/s
Now, comparing the momentum of object A (15.77 kg·m/s) with the momentum of object B (10 kg·m/s), we can see that object A has a higher momentum.
Since momentum is a measure of an object's resistance to change in motion, the object with higher momentum would make you feel worse if you are hit by it. Therefore, in this scenario, object A would make you feel worse if you are hit by it.
