An object dropped from the window of a tall building hits the ground in 12 seconds. If its acceleration is 9.8m/s², what is the height of the window above the ground?
Correct answer: A. 706m
- A. 706m
- B. 353m
- C. 118m
- D. 29.4m
Explanation
Given:- Time taken (t) = 12 s- Acceleration due to gravity (a) = 9.8 m/s2Using the Equation of Motion:Distance = (1/2) * acceleration * time2Calculating the Height of the Window:Distance = (1/2) (9.8)(12)^2Distance = (1/2)(9.8)(144)Distance = (4.9)(144)Distance = 705.6 mThe calculated distance the object traveled from the window is approximately 705.6 m, which is closest to option (a) 706 m.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
