A force with magnitude 30 N acts directly upward from the xy-plane on an object with mass 6 kg. The object starts at the origin with initial velocity v(0) = i − j. Find its position function and its speed at time t.

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
