Question

At launch, a Falcon heavy takes 16.89 seconds to reach a speed of 15 m/s. What is its displacement in the first 16.89 seconds?

Answer 1

The distance traveled by the truck after 15 seconds is 60 meters. The displacement is also 60 meters.

Step-by-step explanation:

In order to calculate the displacement of the truck, we need to find the area under the velocity vs. time graph. Since the graph is a straight line, we can use the formula:

Distance = Velocity x Time

Plugging in the values:

Distance = 4 m/s x 15 s = 60 m

Therefore, the distance traveled by the truck after 15 seconds is 60 meters. Displacement refers to the change in position, which can be calculated by subtracting the initial position from the final position. In this case, since the truck started from rest, the displacement is equal to the distance traveled, so the displacement is also 60 meters.
