AP Physics Final Exam Quiz Bank | Questions and Verified Answers | Grade A (2023/ 2024 New Update) Q: A 50. kg girl on ice skates, initially at rest, pushes against a wall, extending her arms 0.25m for 0.10s causing her to accelerate. Find the magnitude of the force applied by the girl to the wall. Answer: 2500 N Fg=ma x= (1/2) a t2 + v0t a = 2 x / t2 a = 2*0.25 / 0.12= 50 m/s2 Fg=ma = 50 kg * 50 m/s2 = 2500N Third Law Fg=Fw=2500N Q: Assume an astronaut, including his spac...
