6. Padding inside a hockey helmet not only makes it more comfortable to wear, but acts as a safety feature by_ . and Use the following information to answer the next two questions Use the following information to answer the next question (Fill in the blanks by selecting the correct statements.) The graph below represents the force applied on a car during a period of time A 4.92 kg cannonball is shot at 560 m/s [W] from a 687 kg cannon on the i. increasing the stopping time of the helmet during impact deck of a ship. il. decreasing the stopping time of the helmet during impact Force an a Function of Time in. increasing the stopping distance of the helmet during impact iv. decreasing the stopping distance of the helmet during impact Before v. increasing the area of the skull over which the force is exerted vi. decreasing the area of the skull over which the force is exerted Oi, iv, v rope Oi, i. vi Oi, Bi, vi 8. The impulse experienced by the car from t = 1.0s to t = 4.0s is After Oi, BY 07.5 x 103 kg.m/s 5. A 0.0380 kg model rocket is mounted on a nearly frictionless horizontal rail for testing purposes and a 0.0964 kg rocket engine is placed in the 06.5 x 103 kg.m/s model. The rocket engine is designed to give a constant thrust of 13.8 N rope for the 0.856 s burn, until the mass of the engine is reduced to 0.0080 kg 05.5 x 103 kg.m/s and it flames out. 04.5 x 103 kg-m/s 10. Use the information from the above narrative to calculate the velocity of Using momentum to analyze the above scenario is superior to using the the cannon immediately after the cannon ball exits the barrel. The Feet = ma form of Newton's second law mostly because answer, expressed in scientific notation, would be a.bc x 10m/s [E] The values of a, b, c, and d are (Record your 4 digits Oacceleration is not given. 9. The mass of the toy car experiencing the force at 4.00 s described by the answer) above graph is 5.00 kg. If it has an initial velocity of 4.50 x 10 m/s, Oforce is not given. south, and the direction of the force is south, then the final velocity of the car, expressed in scientific notation, would be a.bc x 10 m/s. The Your answer:00 Otime is a factor. values of a, b, c. and d are_ . (Record your four digit answer) both the mass and velocity change 7.
