A2.95 kg object is subjected to three forces that give it an acceleration a with arrow = −(8.00 m/s2)i hat + (6.00 m/s2)j. if two of the three forces are f with arrow1 = (36.6 n)i hat + (16.2 n)j and f with arrow2 = −(12.0 n)i hat + (8.00 n)j, find the third force.

Apositive point charge q is fixed on a very large horizontal frictionless tabletop. a second positive point charge q is released from rest near the stationary charge and is free to move. which statement best describes the motion of q after it is released? assume q stays on the table

Work = force × a. work b. energy c. distance d. momentum

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
