(b) let's say a slingshot is used to shoot a marble straight up from the ground (s0 = 0) with an initial velocity of 11 meters per second. what is the marbles maximum height above the ground

6.17 m

When a slingshot shoots a marble with initial velocity, , it reaches a certain height and starts dropping from their under gravity . At the maximum height, instantaneous velocity,

We would use the following equation of motion to find the maximum height reached:

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

Marble reaches a maximum height of 6.17 m above the ground.
