A pendulum clock is in a lift that accelerates up at 1 m/s² until it reaches a height of 10 m, then decelerates at 1 m/s². Find the time after the start when the clock again shows the right time, in s ( $g = 9.8$ ).
Answer:
8.72
Solution:
$η = 1/9.8$ , $t_{1} = 20 = 4.47$ s. $t = 8.72$ s from the same relation.
