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.
