So normal between ground and lower block will be sum of the weight of the two blocks.
So option A.

2. A 10-kg block is released from rest at point A, as shown below. It slides along a track that is frictionless except for a "sticky" part between points B and C. After its motion along the track, the block hits a spring with spring constant 1500 N/m. It compresses the spring 0.4 m before momentarily coming to rest. 3.00 m 6.00 m-. We have seen in class that when an object moves along a rough surface, the force of...

i posted the firt question please answer the second pic
A 2.0-kg block is released from rest at point A. The track is frictionless except for the rough portion between points B and C. The block travels down the track, hits a spring of force constant 1000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. The mechanical energy of the system at point C is greater than the mechanical energy of the...

(4) A block is released from rest slides down to the bottom of a plane of incline q from a height h; the block attains a speed Vbottom. An identical block is dropped and undergoes free-fall from the same height h and hits the ground with speed Vfree. (a) what is Vfree? (b) Since Vfree must be greater than Vbottom, calculate the coefficient of friction u between the block and the plane. [20 pts]
