Se lanza hacia abajo un cuerpo de masa 2 kg con una velocidad de 1 m/s desde una altura de 10 m. Despreciando los rozamientos con el aire.
¿Cuánto vale y de qué tipo es la energía inicial? ¿Cuánto vale y de qué
tipo es la energía final? ¿Qué velocidad lleva cuando ha recorrido 3 m?
¿Con qué velocidad impacta con el suelo?

Given that,

Mass = 2 kg

Height = 10 m

Speed = 1 m/s

We need to calculate the initial energy

Using formula of potential energy

We need to calculate the final energy

Using formula of kinetic energy

Put the value into the formula

We need to calculate the velocity when it is traveling 3 meters

Using conservation of energy

Put the value into the formula

Hence, The initial and final energy are 196 J and 1 J.

The speed of the particle is 7.76 m/s.
