A2.50kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0350m . the spring has force constant 895n/m . the coefficient of kinetic friction between the floor and the block is 0.45 . the block and spring are released from rest and the block slides along the floor. what is the speed of the block when it has moved a distance of 0.0150m from its initial position? (at this point the spring is compressed 0.0200m .)

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.)
