Suponiendo que el movimiento de un cuerpo se interpreta según la ecuación:

Y=3t²-2 determina la velocidad media considerando los 5 primeros segundos de caida

Average speed = 15

Step-by-step explanation:

To find the speed of the body, we can take the position equation and take the derivative in relation to time:

Speed = dY/dt = 2*3*t = 6t

Then, we need to find the speed at t=0 and the speed at t=5:

Speed (t=0) = 6*0 = 0

Speed (t=5) = 6*5 = 30

Now, we just need to make the average of both speeds:

Average = (0 + 30) / 2 = 15
