<u>Answer:</u>
Displacement after 1 second = 4.9 m
Displacement after 2 seconds = 19.6 m
Displacement after 3 seconds = 44.1 m
Velocity after 1 second = 9.8 m/s
Velocity after 2 seconds = 19.6 m/s
Velocity after 3 seconds = 29.4 m/s
<u>Explanation:</u>
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Height of building, displacement = 381 meter
Initial velocity = 0 m/s
Acceleration = Acceleration due to gravity = 9.8
Displacement after 1 second =
Displacement after 2 seconds =
Displacement after 3 seconds =
We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Velocity after 1 second = 0 + 9.8 * 1 = 9.8 m/s
Velocity after 2 seconds = 0 + 9.8 * 2 = 19.6 m/s
Velocity after 3 seconds = 0 + 9.8 * 3 = 29.4 m/s
