Question 7 A stationary ball is hit with an average force of {2.80x10AB} N. If the ball has mass (5.2x10A2] grams, and the final velocity is (1.600x10A1] me, what is the interaction time, At. in seconds? Give your answer to two significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Question 8 Calculate the magnitude of the impulse if a ball of mass 433 grams, and initial velocity +6.5 m/s is struck back on the same path with a final velocity of -8.3 me. Use a single digit of precision for your answer. Your Answer: Answer Question 9 An object of mass 6.2 kg, with an initial velocity of -9.9 i m/s, is hit with an average force of 388 i Newtons, with an interaction time of 148 milliseconds. Find the final velocity of the object in m/s. You do not need to enter units or the unit vector. Give your answer with a single digit of precision. Your Answer: Answer Question 10 A stationary object of mass 4.0 kg is hit with an average force of 71.1 N. The interaction time At is 233 milliseconds. Calculate the final speed of the object in m/s, with one digit of precision. Your
