Final answer:
According to Newton's 3rd Law of Motion, the trampoline will apply the same force back onto you.
Step-by-step explanation:
According to Newton's 3rd Law of Motion, if you apply the force of your body down onto a trampoline, the trampoline will indeed apply an equal and opposite force back onto you. This means that when you jump on a trampoline and push down with a certain force, the trampoline will push back up with an equal force, propelling you into the air.
