Question
what is the force of a 5.0 kg chair that was thrown out a window with an acceleration of 10.0 m/s2?
5.0 n
10.0 n
20.0 n
50.0 n
if you increase the force on a hot wheels car (for example increasing the ramp height), the acceleration will
increase
decrease
Step1: Identificar la fórmula
Usamos la segunda ley de Newton $F = ma$, donde $F$ es la fuerza, $m$ es la masa y $a$ es la aceleración.
Step2: Sustituir valores
Dado que $m = 5.0$ kg y $a=10.0$ m/s², entonces $F=(5.0\ \text{kg})\times(10.0\ \text{m/s}^2)$.
Step3: Calcular la fuerza
$F = 50.0$ N.
Para la segunda pregunta, según la segunda ley de Newton $F = ma$, si la masa $m$ es constante y aumentamos la fuerza $F$, entonces la aceleración $a$ aumentará.
