Una bala de cañón se dispara horizontalmente con una velocidad de 120m/s, desde lo alto de un acantilado de 250m de altura, sobre el nivel de un lago, tal como se muestra en la figura.
me podrian ayudar es que no entiendo con procedimiento plis

a) Que tiempo tarda la bala en caer al agua

b) Cuál será la distancia horizontal que alcanza la bala

c) Que distancia horizontal ha alcanzado la bala al cabo de 5s.

d) Que distancia ha descendido la bala al cabo de 5s.

e) Respecto del punto de lanzamiento, que coordenadas tendrá la bala, después de 5s.

Prompta snowboarder stands at the top of a hill and decides to see if he can increase his speed on his next trip down the slope. describe one thing the snowboarder could do to incrlase his speed on the slope. explain why this would cause his speed toincrease relate one of newton's laws to this problem.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?
