The drawings below show four objects that are acted upon by different forces. The direction of the forces are represented by the arrows, and the units of the forces are in newtons (N). Based on Newton's law of inertia, which object is moving at a steady or even speed, assuming that all four objects are sitting on a frictionless surface?

Both independent and dependent clauses

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
