Aprofessional boxer hits his opponent with a 1025-n horizontal blow that lasts 0.150 s. the opponent's total body mass is 116 kg and the blow strikes him near his center of mass and while he is motionless in midair.
determine the following.
(b) the opponent's final velocity after the blow
1.29 incorrect: your answer is incorrect. try to express the impulse in terms of the force and time the force acts and also in terms of the mass and speed. then see if you can combine these two expressions for the impulse to determine the final speed. m/s
(c) calculate the recoil velocity of the opponent's 5.0-kg head if hit in this manner, assuming the head does not initially transfer significant momentum to the boxer's body.
30.0 incorrect: your answer is incorrect. if the blow is to the head rather than the body, how does your solution to part (b) get modified? m/s

Three archers each fire four arrows at a target. joe’s four arrows hit at points 10 cm above, 10 cm below, 10 cm to the left, and 10 cm to the right of the center of the target. all four of moe’s arrows hit within 1 cm of a point 20 cm from the center, and flo’s four arrows hit within 1 cm of the center. the contest judge says that one of the archers is precise but not accurate, another archer is accurate but not precise, and the third archer is both accurate and precise. which description applies to which archer? explain

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
