You know what instead i'll put the questions together for 60 !

1. solve d = rt for r
2. solve p = 144p divided by y for p
3. solve r = cs divided by d for c
4. solve p = a + b + c for b
5. solve t = m - n for n
6. solve a = a+b divided by 2 for b

show substitution for all questions, not just the answers.
include the answers for all the questions and how you solved the questions.

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?
