There is an object that is in equilibrium even though it is known that there is a force applied to it.
a. What is meant by “equilibrium”?
b. If you have known that there is a force applied to it but the object is still in equilibrium, what inference could you draw (what can you deduce)? Use Newton’s Laws to support your answer.
c. Can you say if the object is at rest or moving? Explain.

The scenario The conversion of ammonia to hydrogen and nitrogen is not very efficient, even though it's only weakly endothermic (~11 kJ/mol). The addition of a solid metal catalyst can speed up the reaction. The rate law for the decomposition of ammonia is expected to be zero order with these metals at relatively low pressure and high temperatures. For example, on solid platinum the rate law is Rate = k[NH3]° = k. As the total pressure increases, however, the reaction...

An object of mass m is at rest in equilibrium at the origin. At t=0 a new force F⃗ (t) is applied that has components Fx(t)=k1+k2y,Fy(t)=k3t, where k1, k2, and k3 are constants. Part A Calculate the position r⃗ (t) vector as function of time. Part B Calculate the velocity v⃗ (t) vector as function of time. I know that you have to derive to figure out these equations im just not sure where to start, help would be much...

Question 16 A An object of known mass M with speed vo travels toward a wall. The object collides with it and bounces away from the wall in the opposite direction in which the object was initially traveling. The wall exerts an average force Fo on the object during the collision. A student must use the equation Ap= FAt to determine the change in momentum of the object from immediately before the collision to immediately after the collision. Which side...

Just question2(a) please. Thanks
2. An 10 kg object is hung from a spring attached to a fixed support. The spring constant of the spring is k = 40 N m-1. Suppose an external downward force of magnitude f(t) = 20e-2t N is applied to the object, and damping due to air resistance occurs with damping constant B = 40 N s m-1. Let y(t) denote the distance in metres of the object below its equilibrium position at time t...
