Answer:
0.29713 m/s
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
v = Velocity
r = Radius = 18 mm
By balancing the forces in the system we have
![mg-N=\dfrac{mv^2}{r}\\\Rightarrow mg-\dfrac{mg}{2}=\dfrac{mv^2}{r}\\\Rightarrow v=\sqrt{r(g-\dfrac{g}{2})}\\\Rightarrow v=\sqrt{0.018\times (9.81-\dfrac{9.81}{2})}\\\Rightarrow v=0.29713\ m/s](https://tex.z-dn.net/?f=mg-N%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D%5C%5C%5CRightarrow%20mg-%5Cdfrac%7Bmg%7D%7B2%7D%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7Br%28g-%5Cdfrac%7Bg%7D%7B2%7D%29%7D%5C%5C%5CRightarrow%20v%3D%5Csqrt%7B0.018%5Ctimes%20%289.81-%5Cdfrac%7B9.81%7D%7B2%7D%29%7D%5C%5C%5CRightarrow%20v%3D0.29713%5C%20m%2Fs)
The velocity of the coaster is 0.29713 m/s
Answer:
(35 N - 10 N)/8kg = 3.125 m/s^2
Explanation:
The formula for Force is:
Force = Mass*Acceleration
(Force is equal to Mass times Acceleration)
Since we're told to find the acceleration of the box. We make acceleration the subject of the equation:
Acceleration = Force/Mass
(Acceleration equal to Force divided by Mass)
We know that the force are 35 N forward and 10 N backward, and the weight of the box is 8kg.
= (35 N - 10 N)/8kg
The reason that 35 N minus 10 N is because the 10 N is pushing the box backward.
= 25 N/8kg
= 3.125 m/s^2
Hope it helps :DD
Answer:
1362000 kgm/s
Explanation:
So the total mass combination of the plane and the people inside it is
M = 35000 + 160*65 = 45400 kg
After 15 seconds at an acceleration of 2 m/s2, the plane speed would be
V = 2*15 = 30 m/s
So the magnitude of the plane 15s after brakes are released is
MV = 45400 * 30 = 1362000 kgm/s
Acceleration(a) is the change in velocity(Δv) over the change in time(Δt). so just divide your velocity and time.
