An object slides along a curved track of negligible friction, as shown in the figure. The potential energy U of the object as a
function of the position x is shown in the graph. The object starts at rest at x=0. Which of the following is a correct claim about the motion of the object?
(Would prefer an explanation, but it's not necessary)
A) The kinetic energy of the object is approximately the same at x=2m and x=5m.
B) At x=2m, the object has more potential energy than kinetic energy.
C) The object comes to rest when x=5.5m.
D) The rate of change of the potential energy is a minimum at x=0m.
E) The object achieves its maximum speed at approximately x=3m.

Answer:
the pressure at the depth is 1.08 × Pa
Explanation:
The pressure at the depth is given by,
P = h g
Where, P = pressure at the depth
h = depth of the Pacific Ocean in the Mariana Trench = 36,198 ft = 11033.15 meter
= density of water = 1000
g = acceleration due to gravity ≈ 9.8
P = 11033.15 × 9.8 × 1000
P = 1.08 × Pa
Thus, the pressure at the depth is 1.08 × Pa
