if a 70kg man and a 40kg boy are both running at the same velocity, who has more momentum?
momentum is the product (multiplication) of mass and velocity
Momentum is calculated by multiplying an object's mass by its velocity. In this case, the man has a mass of 70kg and the boy has a mass of 40kg. However, since both are running at the same velocity, their velocities are equal. Therefore, the man, who has a greater mass, has more momentum than the boy.
To determine who has more momentum, we first need to understand the concept of momentum. Momentum is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be expressed as:
p = mass × velocity
Given that a 70kg man and a 40kg boy are both running at the same velocity, we can compare their momenta to determine who has more. Let's calculate their individual momenta:
For the man:
mass = 70kg
velocity = same as the boy's velocity
P(Man) = mass × velocity
Similarly, for the boy:
mass = 40kg
velocity = same as the man's velocity
P(Boy) = mass × velocity
Since both the man and the boy are running at the same velocity (which we assume to be constant), we can see that the person with a higher mass will have more momentum, as momentum is directly proportional to mass.
Therefore, the 70kg man will have more momentum compared to the 40kg boy, assuming both are running at the same velocity.
Men = 70kg x 10 m/s = 700 kg*m*s
Boy = 40 gk x 10 m/s = 400 kg*m*s
Horse = 400 kg x 10 m/s = 4000 kg*m*s
Horse = 400 kg x 15 m/s = 6000 kg*m*s
Cheetah = 60 kg x 25 m/s = 1500 kg*m*s
