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.

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
