An iron robot falls from rest at a great height. Neglecting air resistance, what is its speed after it has fallen for 3.5 seconds? A) 9.8 m/s B) 9.8 m/s² C) 13.3 m/s D) 34.3 m/s

Question

Quizplus · Accepted Answer

The speed of the robot after falling for 3.5 seconds can be calculated using the formula $v = gt$, where $g$ is the acceleration due to gravity (approximately $9.8 \, \text{m/s}^2$) and $t$ is the time in seconds. Substituting the given values, $v = 9.8 \, \text{m/s}^2 \times 3.5 \, \text{s} = 34.3 \, \text{m/s}$.
