Question

Not sure if anyone can help or not..
If the ball shown in the figure lands in 1.0 s, about what height was it thrown from?

Answer 1

15.

Answer 2

@Loginusernamed How do you figure out that?

Answer 3

Take a ruler measure the 25M then measure the ?M then figure out.

Answer 4

I know this is a physics based question, I wasn't sure if there was a way to do it that way.

Answer 5

Uhh if D=SxT that distance is 25=_x_?

Answer 6

Use kinematics equation
\(Y=v_0 t-(1/2)gt^2\)
where \(v_0\)=0 = initial vertical velocity
and g=9.81 m/s^2 = acceleration due to gravity.

Answer 7

Hmm - Its been a long time but i think you can use the gravity equations to do this:-
height = u + 0.5*g*t^2

u = initial vertical velocity = 0, g = 9.8 m s-3 and t = 1
so h = 4.9* 1^2 = 4.9 m

Answer 8

* 9.8 m s-2

Answer 9

@welshfella I was thinking that it was approx. around 5. BUT I had guessed, I needed to see someone work it out. Much thanks!! :D
