The force of a particle moving in a circular motion is:
F=ma
where m is the mass and a is the centripetal acceleration, which is expressed as:
a=v²/r
<span>where v is the speed and r the distance between the particles. You use these equations, by substituting the values given in order to solve the problem.</span>
Horizontal forehead wrinkles are caused by contraction of the frontalis muscles. The frontalis muscles are two large fanlike muscles that extend from the eyebrow region to the top of the forehead. I think this is the answer
Velocity is distance/time
so 150/7200=.0208km/s
unless you have to convert it to miles or something else. but use the formula!
Answer:
Net force on the wagon is 200 N
Explanation:
As we know by Newton's II law that net force on the system of mass is given as product of mass and acceleration
Here we know that
mass = 100 kg
a = 2 m/s/s
now we have
