The answer is: In the graph of displacement versus time, for something moving at a constant positive velocity, the line is straight and is going up. You can see it in the graph attached.
The explanation is shown below:
In a graph of displacement versus time, the displacement is on the y-axis and the time is on the x-axis. This type of graph that represents an object moving at a constant positive velocity, shows a linear function where the lines is straight and goes up (As you can see in the graph attached).
Then, the slope of the line is the velocity of the object and the y-intercept is the initial position.
KE=1/2mv^2 - equation for kinetic energy KE=(1/2)(0.12 kg)((7.8 m/s)^2 - plug it into the formula KE=(0.06 kg)(60.84 m/s) - multiply 1/2 to the mass and square the speed KE= 3.7 J - answer Hope this helps
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles. Hopefully this helps:)
Newton's second law says that the acceleration of an object is produced by the force exerted on it. Having this in mind, if you hit a baseball with a bat it will <u>accelerate according to the applied force.</u>
