The speed of the runner is 300 m /38 seconds. You can simplify this answer to be about 7.9 m/s
<span>Force = Work done / distance = 4Nm / 2m = 2N</span>
Newton's 3 laws are...
inertia: things tend to continue to do what they are doing.
Change: to make something change you need a force to change it. the force needed = the mass times its acceleration
<span>
Resistance: When you push on something, it pushes back.
