The equations for free fall near the surfaces of Man and Jupiter Cs in meters, tin seconds) are: Mars, s = 1.86t/2; Jupiter, s = 11.44t/2• How long would it take a rock falling from rest to reach a velocity of 16.6 m/sec (about 60 km/h) on each planet?

the equation for free fall at the surface of a celestial body in outer space(s in meters,t in seconds) is s=4.43t².How long does it take a rock falling drom rest to reach a velocity of 22.2 m/sec on this celestial body in outer space?

Vertical Motion In Exercises 97 and 98, use the position function for free-falling objects.

A projectile is shot upward from the surface of Earth with an initial velocity of 120 meters per second. What is its velocity after 5 seconds? After 10 seconds?

Lunar Gravity On the moon, the acceleration of a free-falling object is meters per second. A stone is dropped from a cliff on the moon and hits the surface of the moon seconds later. How far did it fall? What was its velocity at impact?
