Answer:
18.5 m/s
Explanation:
Take down to be positive.
Given:
Δy = 10.0 m
v₀ = 12.0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (12.0 m/s)² + 2 (10 m/s²) (10.0 m)
v = 18.5 m/s
B.) <span>Newton’s second law states that to increase acceleration, you "Increase Force"

Answer:
La velocidad de la luz en el vacío es una constante universal con el valor de 299 792 458 m/s (186 282,397 mi/s),aunque suele aproximarse a 3·108 m/s. Se simboliza con la letra c, proveniente del latín celéritās (en español, celeridad o rapidez).
¿Cuál es la consecuencia que a velocidad de la luz sea constante?
Respuesta. En modificaciones del vacío más sutiles, como espacios curvos, efecto Casimir, poblaciones térmicas o presencia de campos externos, la velocidad de la luz depende de la densidad de energía de ese vacío.
If an object has more kinetic energy then its going to take more energy to stop it. a larger car has obviously more mass, meaning more kinetic energy, and a smaller car obviously wouldnt have as much energy, so it would take less to stop it. therefore, the larger an object is, the harder it is to stop. hope i helped :)
More massive attacking objects speed slows down and it transfer its some kinetic energy to less massive target objects whereas less massive target objects starts its motion
