Equations F= -kx F= m x a or F= m x g g= -9.8 m/s2 When a 0.50 kg-object is attached to a vertically supported spring, it stretches 0.10 m from the equilibrium position. Find k for the spring.

A.
49

B.
-49

C.
.050

D.
-0.05

A. 49

Explanation:

It is always nice to draw a free body diagram to visualize what is going on. (Or that is what my physics teacher told me haha)

Since you are given F=mg, you can substitute your given values (g=-9.8 and m=0.5) to solve for force.

F = -9.8 x 0.5 = -4.9 N

Then substitute -4.9 N and your given displacement (x=0.1) into your given equation to solve for the spring constant (k).

-4.9=-k(0.1) = -4.9/0.1 = -49

-49 = -k, so -49/-1 = 49

k=49

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
