Question 9 (1 point) Compared to a sports car moving at 30 km per hour . the same sports car moving at 90 km per hour has __ a three times as much momentum b a decrease in momentum C the same momentum d twice as much momentum Question 10 (1 point) During the wall vs. bed sheet experiment, a 0 .03 kg egg is thrown at the wall with a force of 6N. The time of impact was 0.06 seconds, what was the impulse exerted on the egg. a 120Ncdot s b 0.36Ncdot s C 3.6Ncdot s d 12Ncdot s

Question 9:The momentum of an object is given by the formula: Since the mass of the sports car remains constant, the momentum is directly proportional to its velocity. Therefore, if the velocity of the sports car increases from 30 km/h to 90 km/h, the momentum will also increase by a factor of 3.So, the correct answer is:a) three times as much momentumQuestion 10:Impulse is defined as the change in momentum of an object, which can be calculated using the formula: Given that the force exerted on the egg is 6 N and the time of impact is 0.06 seconds, we can calculate the impulse as follows: So, the correct answer is:b) 0.36 N·s
