A cat is walking down a sidewalk and spots a dog in a nearby yard the cat starts to run in the opposite direction and then quickly climbs a tree which of the following changes most accurately describes the movement of the cat a. change in speed b. change in distance c. change in velocity or D change in motion

I'm not sure, but I would say change in speed.

W = 882.9[J]

Explanation:

In order to be able to calculate the work, we must first calculate the force necessary to lift the box. Since the necessary force is equivalent to the weight of the box, we can determine the weight of the box by means of the product of mass by gravitational acceleration.

where:

w = weight [N]

m = mass = 30 [kg]

g = gravity acceleration = 9.81 [m/s²]

Now, the work can be calculated multiplying the force (weight) by the distance [m]
