If the arrow was fired in a direction making an angle x with the horizontal, and assuming that acceleration due to gravity is 32 feet per second^2 ijn the downward direction, then its height at time t iss(t) = 160*sin(x)*t - 16*t^2.
let v = initial velocity and height = h then
h = vt -16t^2

Take acceleration of gravity = 9.8 m/s2 .The ball stops rising and starts falling in (100/9.8) seconds.It returns to the height of the bat in 2 x (100/9.8) = 20.408 seconds. (rounded)
I assume you refer to the formula distance = velocity x time. If an object moves upward, the distance would become the height.
The ball does not return to its initial height after bouncing. So the height it reaches after the first bounce will be a fraction of the initial height, etc. This is a geometric sequence with common ratio 5/8.
In that case, you don't have enough information.
4ft*Ns=H
height=acceletation(t^2) + velocity(t) + initial height take (T final - T initial) /2 and place it in for time and there you go
4h
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.
initial velocity of the kick = 28.06 m/s
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 .
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.
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.

To answer this question one would need to know the rock's initial height and velocity.
The answer depends on what gas the balloon contains, its initial velocity and the forces - gravity, buoyancy, cross-wind - acting on it.
Since the equation for time=sqrt(2h/g) set 2 seconds for time and 9.8 for gravity so 2=sqrt(2h/9.8) clear the sqrt by squaring both sides 4= 2h/9.8 9.8*4 =2h (9.8*4)/2 = height. now that you have the height, you can do v=distance/time v=height from the equation prior/2 seconds i hope that works..
