A 85.1 kg black bear falls off a branch 6.13 m off the ground. She manages to catch another branch 3.05 m off the ground, which bends a maximum of 46.1 cm. What is the stiffness (spring constant) of the branch

K = 1809 N/m = 1.809 KN/m

Explanation:

The spring constant can be given by the following formula:

K = F/ΔL

where,

K = Spring Constant = ?

F = Force Applied

ΔL = Change in Length or the given dimension

Therefore, in this case:

ΔL = 46.1 cm = 0.461 m

and the force will be equal to the weight of the object:

F = W = mg = (85.1 kg)(9.8 m/s²)

F = 833.98 N

Therefore,

K = (833.98 N)/(0.461 m)

K = 1809 N/m = 1.809 KN/m

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
