If I’m understanding this. Th reason why the ball can resist gravity’s pull is because the force used to throw it up was greater than gravity’s pull on it. BTW, gravity’s pull is 9.8m/s. So it would have to be greater than that
This is a problem that can be solved using free-fall motion analysis. Since the displacement (2.9m) is given, we can use the following equation to solve for the impact speed:
V^2 = 2gh
V = sqrt (2*9.8*2.9)
V = 7.54 m/s
Metamorphic Rock - Forms when pressure, temperature, or chemical processes change existing rock. Igneous Rock - forms when magma or lava cools and hardens to become solid. Sedimentary Rock - Form when minerals that form from solutions or sediment from older rocks get pressed and cemented together. The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Hope this helps!
Answer:
the maximum force will be equal to 134.84 N
Explanation:
We have given mass m = 43 kg
Coefficient of static friction 
Acceleration due to gravity 
We have to find the maximum force which , when applied there is no movement of crates
This maximum force will be equal to frictional force
Frictional force is given by 
So the maximum force will be equal to 134.84 N
The magnetic force on a moving charge, depends on three four things: the magnitude of the charge, the velocity of the charge, the strength of the magnetic field, and the angle between the velocity and the magnetic field.
