*please help* Six Flags New coaster -"The Titan" - WOW what a coaster! - lifts you and your
companions (total mass car and riders = 2.20 x 10^4 kg) to a height of 77.7 m up the first hill. What is the work done by the ride to get you to the top of the hill?

If y gets smaller as x gets bigger and y have an relationship?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Which describes increasing the efficiency of energy resource
