Answer:
The answer is below
Explanation:
Equation of motion is a term in physics that is used in explaining the characteristics of a physical system concerning its motion while considering the period.
The First Equation of Motion is given as v = u + at
Here, a = acceleration, v = final velocity, u = initial velocity, and t = time
To deduce it algebraically, it is written as
a = (v - u) ÷ t
Therefore, it can be repositioned to => v = u + a * t
Answer: His weight plus the centripetal force must equal 1170 N
Explanation:
83.0 [g + (v^2 / r)] = 1170
v^2 / 18.0 = (1170 / 83.0) - 9.81
First calcualte the acceleration =V/t=12/12=1m/s2
Second calcualte the net force according to the Newton second law
F=ma=710x1=710N
The velocity is (3,000/5) = 600 miles per hour west .
<span>If the core of a supernova explosion contains three or more solar masses of matter, the core will most likely become a black hole. Black holes form when stars explode, and create these areas of such intense gravitational fields that absolutely nothing can escape them if they approach a black hole. Anything near a black hole will disappear without a trace and possibility of ever being found.Although we still don't know much about black holes, we certainly know that nothing can survive the impact.</span>
