1. On April 15,1912, the Luxury cruiseliner Titanic sank after running into an iceberg. What momentum would the 4.23 x 108 kg ship have imparted the iceberg if it had hit the iceberg head-on with a speed of 11.6 m/s?
2. Auto companies frequently test the safety of automobiles by putting them through crash tests to observe the integrity of the passenger compartment. If a 1000 kg car is sent toward a cement wall with a speed of 14 m/s and the impact brings it to a stop in 0.08 s, with what average force is it bought to rest?
3. Rhonda, who has a mass of 60.0 kg, is riding at 25 m/s in her sports car when she must suddenly slam on the brakes to avoid hitting a dog crossing the road. She is wearing a seatbelt, which brings her body to stop in 0.400 s,
a) What average force did the seatbelt exert on her?
b) If she had not been wearing her seatbelt, and the windshield had stopped her head in 0.001 s, what average force would the windshield have exerted on her?
