Uma motocicleta tem velocidade inicial de 20 m/s e adquire uma aceleração constante e igual a 2m/s². Calcule sua velocidade em km/h ao percorrer 100 m. V2 = Vo2 + 2.a.ΔS

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
