Help on Making an Egg capsule that survives a about 100 feet launch from catapult. You can only use one plastic bag, one Styrofoam cup, one ziplock bag, 7 popsicle sticks, 7 cotton balls, 9 packing peanuts, 9 straws, 9 yards of string, 1 yard of string, 1 egg and 1 yard of tape. And no, you can't hard boil the egg. Any ideas or pictures?

Explanation:
A transverse wave is a wave in which the oscillation of the particles occur in a direction perpendicular to the direction of motion of the wave.
The amplitude of a transverse wave is the maximum displacement of the wave with respect to the equilibrium position.
The crest of a wave is the position of maximum displacement on the positive side, while the trough of a wave is the position of maximum displacement on the negative side.
This means that the amplitude of a wave is equal to the distance between a crest (or a trough) and the equilibrium position.
Therefore, we have:
where:
d is the distance between the top of a crest and the bottom of a trough
A is the amplitude of the wave
Here we have:
A = 2.4 m
So, we find

There are so many factors which works to stop a car from sinking into road surface. One is reaction force other factors are density of material from which the car is made of, mass and shape of car.but the most important force is the reaction force. According to the Newton's 3rd law of motion:- every force have equal force acting in opposite direction.
However I like to think of it as the reaction force, as it is the force that is a result of obeying Newton's 3rd law ("For every action, there is an equal and opposite reaction"). The upward force from the ground is the reaction to the downward force of gravity.

What is the normal force on the cart?
Answers
Answer:
The "normal force" on the "cart" 63.893 N.
Explanation:
To find normal force on the cart, use the equation
Normal force = mg + F sinx,
“m” being the object's mass,
“g” being the acceleration of gravity,
“x” being the angle of the cart
Given values
M = 7.33 kg
F = 14.7 N
Substitute the values in above equation
Normal force = (7.33 × 9.8) + 14.7 sin(-32.7°)
Normal force = 71.834 + 14.7 × (-0.5402)
Normal force = 71.834 - 7.94094
Normal force = 63.893 N
The "normal force" on "the cart" 63.893 N.
The normal force on the cart is 79.7 N
Explanation:
In order to find the normal force, we have to analyze the forces acting on the cart on the vertical direction.
In the vertical direction, we have the following forces:
The weight of the cart, downward, of magnitude , where m is the mass of the cart and g is the acceleration of gravity
The normal force on the cart, upward, we indicate it with N
The component of the pushing force acting in the vertical direction, downward, of magnitude , where F is the magnitude of the force and is the angle of the force with the horizontal
Therefore, the equation of the forces on the cart in the vertical direction is:
where the net force is zero since the cart is balanced in the vertical direction. We have:
We take the angle as positive since we are already considering the downward direction in the equation.
Substituting and solving for N, we find the normal force:
