If two objects with different masses are pushing each other, which exerts the greater force?

A. The object with the greater mass exerts the greater force on the smaller object because the larger object has more inertia.

B. It is impossible to tell which object exerts the greater force unless we know which object accelerates.

C. The object with the smaller mass exerts the greater force on the larger object because it requires more force to make the larger object move.

D. They both exert the same amount of force on each other regardless of their mass, but in opposite directions.

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.
