Si la velocidad de un bloque unido a un resorte está dada por la ecuación V= 7 cos(8t+0,5π)m/s, determine el módulo de la aceleración máxima si w = 8 rad/s

Thank you lord lord thank lord lord

The atmosphere consists of five layers and is responsible for Earth's weather. Even though it seems like air is made of nothing, it consists of particles too small to be seen. All these particles have weight that push down on Earth. The weight of air above us is called air pressure.
