Distance Travelled by a Free Falling Object
What is the distance travelled by a free falling object in the first second?
a) 4.9m b) 9.8m c) 19.6m d) 10m
The correct answer is option a) 4.9m.
When a free falling object is in motion, the distance travelled in the first second can be calculated using the formula:
s = -1/2 * g * t^2
Where: s = distance travelled g = acceleration due to gravity (9.8m/s^2) t = time (1s in this case)
Plugging in the values:
s = -1/2 * 9.8 * (1)^2
s = -4.9(1)
Since distance cannot be negative in this context, the distance travelled in the first second is 4.9m.
