Sagot :

The horizontal displacement of the backpack as it falls is 765 m.

Data obtained from the question

From the question given above, the following data were obtained:

  • Initial velocity (u) = 85 m/s
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Time (t) = 9 s
  • Horizontal displacement (s) =?

How to determine the horizontaal displacement

The horizontal displacement of the backpack can be obtained as follow:

s = ut

s = 85 × 9

Horizontal displacement = 765 m

From the calculation made above, we can see that the horizontal displacement (i.e distance from the car) were the backpack will land is 765 m. Thus, the backpack will not land on your car. Hence, you do not need to move the car.
