I'm pretty sure the energy an object acquires when exposed to a force is known was potential energy.
I think it was Isaac Newton
Answer:
268N
Explanation:
The upward force acting on the block are the reaction and the hooked table..
The total normal force acting = normal reaction + 24N
Note that the normal reaction is always equal the weight of the table
Hence the normal force acting in the block is 244.0+24 = 268.0N
