If the height of a lab table in a classroom is 0.60 m, how long would it take for a ball launched off the edge of these tables to reach the floor?

Explanation:

Using the equation of motion S = ut+1/2gt² where;

S is the height of the table = 0.60m

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.81m/s²

t is the time taken

Substitute

0.6 = 0+1/2(9.81)t²

0.6 = 4.905t²

t² = 0.6/4.905

t² = 0.1223

t = √0.1223

t = 0.3497

t≈0.35secs

Hence it will take 0.35seconds for a ball launched off the edge of these tables to reach  the floor

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
