Si tengo un elefante de 13 kg y lo empujo 10 m por un suelo rugoso con una fuerza de 15 N: ¿Qué fuerzas están actuando?
Dibuja un diagrama que muestre las fuerzas
¿Cuánto trabajo hice?
Si me toma 37 segundos empujar al elefante, ¿cuál es mi potencia de salida?

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
