Con una rapidez constante de 60 km/h un automóvil recorre una carretera recta de 700 m que tiene una inclinación de 4° respecto a la horizontal un observador nota únicamente el movimiento vertical del auto calcule la magnitud de la velocidad vertical del auto y ve la distancia vertical que recorrió cuál

4.2 m/s, 48.8 m

The magnitude of the vertical velocity of the car is given by:

where

v = 60 km/h is the magnitude of the velocity

is the angle between the road and the horizontal

Substituting into the formula,

The horizontal distance travelled by the car instead corresponds to the height of the road, so it is given by

where

L = 700 m is the length of the road

Substituting,

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
