∆y is change in y (velocity) and ∆x is change in x (time)
So from the graph we see that ∆y is zero and ∆x is also zero (value is changing with same ratio)
∆y/∆x= slope = 0
The total energy of the system is always conserve, therefore at all the point A, B & C the total energy of the skater is same.
Kinetic energy is directly proportional to the velocity, as the skater reaches the top of the pipe, the velocity of the skater would be zero, so there would be no kinetic energy, as he progress down the pipe the velocity of the skater increases, thus kinetic energy increase and highest at the bottom of the pipe, therefore the increasing order of the kinetic energy is C>B>A.
Potential energy is dependent on the height, as the height increases potential energy will also increase. therefore the increasing order of the potential energy is A>B>C.

Answer:
The normal force the ground exerts on the block, F = -300 N
Explanation:
Given data,
The block pulled up with a tension force, T = 100 N
The weight of the block, W = 300 N
The weight of the block is due to the force of attraction of gravitation.
The surface exerts a force that is equal and opposite to the force acting on the block due to gravitation.
The weight of the block,
W = mg
300 N
The normal force the ground exerts on the block,
F = - mg
= - 300 N
Hence, the normal force the ground exerts on the block, F = -300 N
