Question

Hello - 

I don't understand the second question here about whether it was correct to assume that the upper block doesn't slip. Can you help explain it?

2.0-kg block sits on top of an 8.0-kg block under the influence of a force of magnitude 17 N applied to the top block at an angle 0 = 30° as shown. The coefficient of static friction
between the two blocks is 0.50 and friction between the lower block and the floor is negligible.

Common Acceleration
Begin by assuming that the upper block does not slip with respect to the lower block, and calculate the magnitude of the common acceleration of bloth blocks.
a =
1.47 m/s^2
Hint:
............
Do Blocks Stick?
Was it correct to assume that the upper block does not slip with respect to the lower block and that both accelerate to the right? That is, do the block stick together?
O Yes
O No
ONot enough information is given to tell.
Hint:
This problem isn't as simple as the previous one. You will need to determine the value of the friction force. Once you know the value of the friction force, you can apply N2L
to each block separately.
