You are trying to find out how high you have to pitch a water balloon in order for it to burst when it hits the ground. you discover that the balloon bursts when you have pitched it to a height of 16 m. with what velocity did the balloon hit the ground? the acceleration of gravity is 9.8 m/s 2 . the positive direction is up, so the velocity when it hits is negative. answer in units of m/s.

-17.7 m/s

The maximum height achieved by balloon,

The instantaneous velocity at the maximum height,

The balloon free falls under gravity,

Using the equation of motion:

where, is the final velocity, is the initial velocity, is the acceleration and is the distance covered.

Substitute the values:

We will consider only the negative value, as the positive direction is considered upwards.

this is a good question! i'll do some research and come back when i have the answer!

double the distance = divide strength by 4
