O .994 J/g °C
O 987 J/g °C
O .106 J/g °C
O .233J/g °C

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

Anybody wanna ? (picture included? )
