Starting from a location with position vector 𝑟1,𝑥=−17.5 m and 𝑟1,𝑦=23.1 m , a rabbit hops around for 10.7 seconds with average velocity 𝑣𝑎𝑣,𝑥=−2.25 m/s and 𝑣𝑎𝑣,𝑦=1.79 m/s . Find the components of the position vector of the rabbit's final location, 𝑟2,𝑥 and 𝑟2,𝑦 .

Question

Starting from a location with position vector  𝑟1,𝑥=−17.5 m  and  𝑟1,𝑦=23.1 m , a rabbit hops around for  10.7  seconds with average velocity  𝑣𝑎𝑣,𝑥=−2.25 m/s  and  𝑣𝑎𝑣,𝑦=1.79 m/s . Find the components of the position vector of the rabbit's final location,  𝑟2,𝑥  and  𝑟2,𝑦 .
