One end of a horizontal spring with force constant 130.0 n/m is attached to a vertical wall. a 3.00 kg block sitting on the floor is placed against the spring. the coefficient of kinetic friction between the block and the floor is μk = 0.400. you apply a constant force f⃗ to the block. f⃗ has magnitude 88.0 n and is directed 3 toward the wall. the spring is compressed 80.0 cm. (a) what is the speed of the block? (b) what is the magnitude of the block’s acceleration? (c) what is the direction of the block’s acceleration?
