This is Physics 20 (grade 11)- Module 3- Lesson 2 - Newton's Third Law

Question 7 Explain the following observations in the context of Newton's Third Law. Answer saved Marked out of 1) When you push hard against a wall, you move backwards but the wall doesn't move 3.00 anywhere. Flag question 2) If you throw a heavy ball forwards, you feel like you are being pushed backwards. 3) Imagine kicking a rock the size of a soccer ball. The rock barely moves, and your foot is very hurt. Why did you get so hurt even if the rock didn't move much? Paragraph Binitial velocity = 0.00 m/s initial velocity = 0.00 m/s final velocity = -0.23 m/s final velocity = m/s change in velocity = -0.23 m/s change in velocity = m/s time interval over which the force is applied = 0.10 s time interval over which the force is applied = 0.10 s *Note: This is not displayed on the simulation. *Note: This is not displayed on the simulation. calculate the acceleration of skater 1 calculate the acceleration of skater 2: m/s 2 m/s2 mass of skater 1 = 60.0 kg mass of skater 2 = kg calculate the force applied to skater 1: N calculate the force applied to skater 2: N * Round your answer to 2 significant digits.Question 9 Two basketball players run into each other. Player 1 has a mass of 45.0 kg and during the Not yet answered collision, they experience an acceleration of -10.5 m/s2. Marked out of Player 2 has a mass of 60.0 kg. Calculate the acceleration of Player 2 in units of m/s2. Round 2.00 your answer to 1 decimal place. Flag question Answer:Question 10 Airbags are a proven safety device that save many lives each year. However, Not yet answered these lifesaving devices can actually cause serious harm, or even death, if Marked out of they deploy while a small child is seated in their path. 3.00 From the perspective of Newton's first and second law consider the following scenario: Flag question A car (carrying a child as a passenger) collides with an object on the side of the road. The child has a mass of 20 kg. The airbag triggers and expands rapidly. The bag has a mass of 500 g and is traveling at 71 m/s when it collides with the child. The bag strikes the child and over 0.05 seconds the bag's velocity drops to zero. a) Based on Newton's First and Second Laws, determine the acceleration the child will experience. (2 marks). b) Repeat the analysis but this time the bag strikes an adult male with a mass of 80 kg. (1 mark) c) From your answers in (a) and (b), make a general statement about why airbags are more dangerous for child passengers compared to adult passengers (1 mark).t: 6.50 s $1 0.23 mis Xcm -0.04 m $2: 0.31 m's p1 13.89 kg m's P2: 13.89 kg mis KET 1.61 J KEY 2.14 J x1 -1.75m X2 2.26 m Show Blocks Mass 1: 60.0 kg Mass 2: 45.0 kg .
