Question

5. A 3-centimeter-long maple tree seed is falling at a velocity of 120centimeters per second toward the ground. If its velocity stays constant,how far will the seed fall in 1.5 seconds?

Answer 1

The first thing to do is calculate the times it takes with the velocity of 120 and the space traveled (3 cm)

`\begin{gathered} v=(d)/(t) \\ t=(d)/(v) \\ t=(3)/(120)=0.025 \end{gathered}`

Now, we make the following proportion:

`\begin{gathered} (0.025)/(3)=(1.5)/(x) \\ x=(1.5\cdot3)/(0.025) \\ x=180 \end{gathered}`

therefore, the distance is 180 cm
