Um bloco de 6 kg encontra-se em repouso e apoiado sobre um plano inclinado em 30° em relação ao solo considerando a gravidade igual a 10 metros por segundo determine o módulo da força que o plano inclinado exerce sobre o bloco

The slope of a velocity time graph over any interval of time gives the during that interval

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
