How Do You Calculate Forces and Time for a Falling Object?

[playW/Gravity]

Homework Statement

The height of which it will be dropped 5.1816m, then the mass is 0.057kg. and the gravity is 9.8m/s^2 .What is the force downward? what's the net force and what's the up force? and what's the time to hit the ground?

Homework Equations

Fg=m*g

The Attempt at a Solution

Fg=.057kg*9.8=.5586 N
thats all i know how to do thanks

The only other thing that may be significant is are resistance once the mass starts falling. If the mass is a lead pellet, air resistance won't have much significance. If the pass is a huge block of polystyrene, air resistance will be significant.
The only thing you know for sure is that air resistance on a falling object is directed up.

its an egg , but how do u fund the other forces

I would have thought gravity and iar resistance is all.

For all situations, remember the following.

Field forces arising from Gravity, electrostatics and magnets act without contact.

All other forces are contact forces - something pushing, or pulling via a thread/string.

For the egg you can likely rule out electrostatics and magnets, so we have gravity plus anything else that is touching the egg.

I would like to clarify that the force downward on a falling object is called the weight or gravitational force, which is calculated using the equation Fg = m*g, where m is the mass of the object and g is the acceleration due to gravity (9.8m/s^2 on Earth). In this case, the weight of the object would be 0.5586 N.

The net force on the object would be the sum of all the forces acting on it, which in this case would only be the weight. Since the object is falling, there is no up force acting on it.

To calculate the time it takes for the object to hit the ground, we can use the equation d = 1/2 * g * t^2, where d is the distance the object falls (5.1816m in this case) and t is the time. Rearranging the equation, we get t = √(2d/g). Plugging in the values, we get t = √(2*5.1816/9.8) = 1.15 seconds.

It is important to note that this calculation assumes the object is falling in a vacuum with no air resistance. In reality, air resistance would affect the time it takes for the object to hit the ground.
