What is the initial arclength of a pendulum when you know the length and mass and max velocity and initial height of the pendulum?

If you know the initial height and the length of the pendulum, then you have no
use for the mass or the velocity. You already have the radius of a circle, and an arc
for which you know the height of both ends. You can easily calculate the arc-length
from these.
And by the way . . . it'll be the same regardless of the mass or the max velocity.
They don't matter.

How many swings a pendulum makes in a second?
That depends on a number of different variables and therefore it cannot be concluded here. It depends on the mass of the object being swung as well as the initial conditions of this object such as the height it is released or the initial velocity by which it was flung.
An object projected up with initial velocity v attains a height h Another object projected up with initial velocity 2v will attain what height?
4h
What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
initial velocity of the kick = 28.06 m/s
What do you need to know to determine how far a projectile travels horizontally?
initial velocity, angle of launch, height above ground When a projectile is launched you can calculate how far it travels horizontally if you know the height above ground it was launched from, initial velocity and the angle it was launched at. 1) Determine how long it will be in the air based on how far it has to fall (this is why you need the height above ground). 2) Use your initial velocity to determine the horizontal component of velocity 3) distance travelled horizontally = time in air (part 1) x horizontal velocity (part 2)
A simple pendulum is hung in a stationary lift and its periodic time is T. what will be the effect on its periodic time T if the lift goes up with uniform velocity v?
Nothing (ignoring effects due to height). If the elevator is moving at a uniform velocity, relativity says the velocity doesn't matter.
What is the equation to calculate the maximum height of an object given an initial velocity and initial launch height?
height=acceletation(t^2) + velocity(t) + initial height take (T final - T initial) /2 and place it in for time and there you go

How to find the height of the projectile launch if the angle velocity and the distance are given?
Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .
. ok v velocity a acceleration but what about you?
if by 'you', you mean 'u' then u is the initial velocity v is the final velocity. you need to know the initial velocity in trajectory question (motion of an object through the air) to find height, acceleration, time etc.
How does height affect the period of a pendulum?
Height does not affect the period of a pendulum.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
What is the rock's approximate velocity just prior to hitting the ground?
To answer this question one would need to know the rock's initial height and velocity.

If the launch angle is 15 degrees and the initial velocity is 50.0 meters per second what is the range?
If the initial velocity is 50 meters per second and the launch angle is 15 degrees what is the maximum height? Explain.
