It takes the policeman 4.0 s to react before accelerating at a rate of the suspect doesn't notice that the policeman is chasing him and continues at the same constant speed how far from the policeman's starting point will they be when the policeman catches up to the suspect? O 1200 m O 810 m O 1050 m O 180 m

Answer 1

Solution D = Distance travelled by the suspect during the reaction t'me ( 4 seconds) = 45X4 = 180 m. so Ś at2 - Vt = 180 5 *X40572 – 457 = 180 OR uost2 - got = 360 +2 - 20+ - 80 = 0 (dividing by 405) t= 20 + 400+ 390 Seconds 2 = 20 + 26.833 = 23.4165 Second, so the distance of the point where the suspect of caught, from the starting point af Police x 415 *(2314165) = 1233.75 m. m 1200 m € 1200 m
