A lemming running 3.22 m/s runs off a horizontal cliff. It lands in the water 7.54 m from the base of the cliff. How much time was it in the air? (Unit = s)

Answer: 2.34s

Explanation:

Given the following:

Horizontal Velocity (V) = 3.22m/s

Horizontal Distance = 7.54m

Therefore, the time spent in the air can be calculated thus:

Using the relation:

Speed = distance / time

3.22m/s = 7.54m / time

Time = 7.54m / 3.22m/s

Time = 2.34s
