A) Acceleration= (282m/s-0m/s)/5.0s= 56.4m/s^2
b) Deceleration=(0m/s-282m/s)/1.40s=201.4m/s^2 (here we reject negative because deceleration already take into account negative)
c) for the first one the multiple will be 5.76g
for the second one it will be 20.6g
Answer:
a = 177.77 [m/s^2]
Explanation:
Este es un problema relacionado con la segunda ley de Newton. La cual nos dice que la sumatoria de fuerzas aplicada sobre un cuerpo debe ser igual al producto de la masa por la aceleración.
De esta manera tenemos:
F = m*a
F = fuerza = 80 [N]
m = masa = 0.45 [kg]
80 = 0.45 * a
a = 80 / 0.45
a = 177.77 [m/s^2]
Answer:true
Explanation:
The lower the refractive index,the faster the velocity of light
Answer: a rubber band
Explanation: A rubber band has no conductivity and no electricity would be able to flow whereas steel and copper and aluminum would be able to allow electricity to flow due to how they are built
