Un carrito con un cañón accionado por resorte dispara verticalmente una esfera
metálica como se observa en la figura (considere el suelo como referencia y que
la bala se libera desde el suelo). Si la rapidez inicial vertical de la esfera es 5.0 m/
s y el cañón se mueve horizontalmente a una rapidez de 0.75 m/s, a) ¿a qué
distancia del punto de lanzamiento la esfera vuelve a caer en el cañón, y b)
esperaría usted que la bala tuviera un movimiento acelerado en el eje horizontal
si el cañón estuviera acelerando al momento de ser lanzado?
