Ice is only thing which is mightier than steel because it can breaks things which are made up of steels like ships but in the sunlight ice melts away it means it cowards away.
Answer:
The net force acting on this object is 180.89 N.
Explanation:
Given that,
Mass = 3.00 kg
Coordinate of position of ![x= 5t^3+1](https://tex.z-dn.net/?f=x%3D%205t%5E3%2B1)
Coordinate of position of ![y=3t^2+2](https://tex.z-dn.net/?f=y%3D3t%5E2%2B2)
Time = 2.00 s
We need to calculate the acceleration
![a = \dfrac{d^2x}{dt^2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7Bd%5E2x%7D%7Bdt%5E2%7D)
For x coordinates
![x=5t^3+1](https://tex.z-dn.net/?f=x%3D5t%5E3%2B1)
On differentiate w.r.to t
![\dfrac{dx}{dt}=15t^2+0](https://tex.z-dn.net/?f=%5Cdfrac%7Bdx%7D%7Bdt%7D%3D15t%5E2%2B0)
On differentiate again w.r.to t
![\dfrac{d^2x}{dt^2}=30t](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%5E2x%7D%7Bdt%5E2%7D%3D30t)
The acceleration in x axis at 2 sec
![a = 60i](https://tex.z-dn.net/?f=a%20%3D%2060i)
For y coordinates
![y=3t^2+2](https://tex.z-dn.net/?f=y%3D3t%5E2%2B2)
On differentiate w.r.to t
![\dfrac{dy}{dt}=6t+0](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdt%7D%3D6t%2B0)
On differentiate again w.r.to t
![\dfrac{d^2y}{dt^2}=6](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%5E2y%7D%7Bdt%5E2%7D%3D6)
The acceleration in y axis at 2 sec
![a = 6j](https://tex.z-dn.net/?f=a%20%3D%206j)
The acceleration is
![a=60i+6j](https://tex.z-dn.net/?f=a%3D60i%2B6j)
We need to calculate the net force
![F = ma](https://tex.z-dn.net/?f=F%20%3D%20ma)
![F = 3.00\times(60i+6j)](https://tex.z-dn.net/?f=F%20%3D%203.00%5Ctimes%2860i%2B6j%29)
![F=180i+18j](https://tex.z-dn.net/?f=F%3D180i%2B18j)
The magnitude of the force
![|F|=\sqrt{(180)^2+(18)^2}](https://tex.z-dn.net/?f=%7CF%7C%3D%5Csqrt%7B%28180%29%5E2%2B%2818%29%5E2%7D)
![|F|=180.89\ N](https://tex.z-dn.net/?f=%7CF%7C%3D180.89%5C%20N)
Hence, The net force acting on this object is 180.89 N.
Answer:
12x²
Explanation:
Product of 4x and 3x
Product means multiplication
4x x 3x = (4x x 3x)
(4x 3) x X x
= 12x²

Answer:
S = 2 π R
R (mean) = 92.9E6 miles
S = 2 * 3.14 * 92.9E6 miles = 5.84E8 miles
