The magnitude is doubled. The direction doesn't change.
Answer:
T = T
Explanation:
The period of a simple pendulum is given by the formula
Where
l - length of the pendulum
g - acceleration due to gravity
The dimension of the physical quantities are given by,
t - T
l - L
g - m/s² - LT⁻²
Substituting in the above equation,
T = 2π √(L / LT⁻²)
Considering only the dimensional units in the equation
T = √(L / LT⁻²)
T = T
This shows that the formula for a simple pendulum is dimensionally consistent, T = T
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 .
