A boy wants to use his slingshot to shoot water balloons into the air. His sling slingshot has a spring constant of 40 n/m and he pulls it back 1.5 m before releasing the water balloon and launching it into the air. If air resistance can be ignored and the water balloon has a mass of 1 kg, what is the approximate maximum height that the water balloon can reach? Recall that g= 9.8 m/s

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
