The position of the car at t=3.0s is 18m from the origin.
the starting point of a quantity at a certain time, let's say t = 0. This is referred to as receiving an "initial condition",
For a car on an amusement park ride, the velocity as a function of time is given by v=at² + bt with constants.
According to the equation above,
- A function of time's derivative is a constant.
- Time affects the velocity.
v = t² + 2t
Since v = dx/dt
dx/dt = t² + 2t
dx = t²dt + 2tdt
Integrating both sides [ integration{ a^nda } = a^(n+1) / (n+1) ]
So , int [ x⁰dx ] = int [ t²dt ] + 2 int [ t¹dt ] ,
Now,
x¹/1 = t³/3 + 2*( t²/2 )
x = t³/3 + t²
For t = s,
x = 3³/3 + 3²
x= 27/3 + 9 = 18 m .

Answer:
W = 588 N
Explanation:
The given question is ,"calculate the weight of a table on the earth whose mass is 60 kg"
The mass of the table, m = 60 kg
We need to find the weight of a table on the earth.
The weight of an object is given by :
W = mg
Where
g is acceleration due to gravity
W = 60 kg × 9.8 m/s²
W = 588 N
Hence, the weight of the table is 588 N.
Answer:
the planet Earth is a good example
Ohm’s law states:
I*R = U
So we just fill in:
U = 11 A * 60 Ω = 660 V
