Question

En un planeta distante,un objeto en caida libre cambia su velocidad de 10m/s a 90m/s en 2 segundos ¿Cual es la aceleración gravitacional de dicho planeta?

Answer 1

a = 40 m / s²

Step-by-step explanation:

For this exercise we can use the vertical launch equations to which these are valid in any system with inertial

v = v₀ + a t

a = (v-v₀) / t

We calculate

a = (90 - 10) / 2

a = 80/2

a = 40 m / s²

This is the value of the planet's gravity acceleration
