11.98 DINAMICA BEER MOVIMIENTO PROYECTIL - Tres niños se LANZAN BOLAS de NIEVE

Summary

In this tutorial, the problem of three children throwing snowballs at each other is solved using basic kinematic equations. The goal is to determine the horizontal velocity and the distance between two children. The process involves analyzing the vertical and horizontal motion of the snowball, applying equations for displacement and velocity, and calculating the necessary values step by step. The tutorial guides the viewer through the calculations and offers a clear understanding of how to approach this type of physics problem, with the final results being the horizontal velocity (15.503 m/s) and the distance between the children (5.124 meters).

Takeaways

• 😀 The problem involves three children throwing snowballs at each other, with child A launching a snowball horizontally with a certain initial velocity.
• 😀 The goal is to determine the horizontal velocity (Bo) and the distance (D) between child B and child C.
• 😀 The reference point is set at child A, where the initial vertical position and velocity are both zero.
• 😀 The vertical displacement between children A and B is given as 1 meter, which is considered negative due to the direction of the reference system.
• 😀 Using the kinematic equation, the time it takes for the snowball to reach child B is calculated to be 0.451 seconds.
• 😀 After determining the time, the horizontal velocity (Bo) is calculated using the equation for horizontal motion: Bo = X / time.
• 😀 The horizontal velocity Bo is found to be 15.503 meters per second.
• 😀 Next, the vertical displacement from child A to child C is given as -3 meters, accounting for the gravitational acceleration of 9.81 m/s².
• 😀 The time for the snowball to travel from child B to child C is found to be 0.782 seconds using the vertical motion equation.
• 😀 The distance (D) between child B and child C is then calculated using the equation D = Bo * time - 7 meters, which results in a distance of 5.124 meters.
