Hint: Is the object accelerating? (If yes,) what is the nature of its acceleration?
D
Hint: First calculate the acceleration using Torricelli's equation. Then, find the force applying Newton's Second Law of Motion.
C
Hint: Find the acceleration employing its formula. Then, calculate the force with Newton's Second Law of Motion.

Hint: a - Use Torricelli's equation to find the acceleration and, after that, find the force with Newton's Seconfd Law of Motion. b - Employ the
a: 11 kN; b: 1.0 s.
Hint: a - Find the acceleration using Newton's Second Law of Motion, then, use the equation of the motion (velocity as a function of time) to calculate the velocity. b - Use Torricelli’s equation to calculate the displacement.
a: 0.29 m s^(-1); b: 1.2 m
