An object starts from rest and falls freely for 40. meters near the surface of planet p. if the time of fall is 4.0 seconds, what is the magnitude of the acceleration due to gravity on planet p?

The magnitude of the acceleration due to gravity on planet P is 5 m/s².

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

Height (H) = 40 m

Time (t) = 4 s

Acceleration due to gravity (g) on planet P =?

The acceleration due to gravity on planet P can be obtained as follow:

H = ½gt²

40 = ½ × g × 4²

40 = ½ × g × 16

40 = g × 8

Divide both side by 8

g = 40 / 8

Therefore, the acceleration due to gravity on planet P is 5 m/s²

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
