The linear momentum of the boy is 80 kg·m/s.
Solución
To find the linear momentum of the boy, we can use the formula for linear momentum, which is given by:
Given:
- Mass of the boy = 40 kg
- Velocity of the boy = 2 m/s
Substitute the values into the formula to find the linear momentum.
Calculate the value by following steps:
Calculate the value by following steps:
- step0: Calculate:

Bonus Knowledge
The linear momentum § of an object can be calculated using the formula
, where
is the mass and
is the velocity. For the boy with a mass of 40 kg walking at a speed of 2 m/s, his momentum would be
. So, the linear momentum is 80 kg·m/s.
Now, imagine if the boy suddenly stops to catch a ball! When he halts, his momentum decreases to zero. This concept is crucial in everyday scenarios, like how different actions, like running or stopping, affect our movement and interactions with the world around us.
