The correct answer is 4 cm :)
Answer:
350 kg m/s
Explanation:
Momentum = mass × velocity
p = mv
p = (100 kg) (3.5 m/s)
p = 350 kg m/s
After putting stuff through google and some calculators, I’d say the answer is C.
The elastic potential energy (Ep) is given by

Data:
Ep = ? (Joule)
k = 20 N/m
x (displacement) = 0.20 m
Solving:




Im pretty sure it’s A eye
