En un m. A.S. La amplitud tiene un valor de 10 centimetros y el periodo es de 2 segundos calcular el valor de la velocidad de 0.8 y 1.4 segundos de haberse iniciado el movimiento

v1=18.46m/s

v2=29.8cm/s

Explanation:

We know that

the equation of the motion is

we can calculate w by using

Hence, we have that

the speed will be

hope this helps!

measure their densities same density, same sub

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
