Question

Tarzan swings through the jungle by hanging from a vine.

part A. Drag words or phrases from each group into the blanks to create a true statement. Immediately after stepping off a branch to swing over to another tree, Tarzan's acceleration(-----blank1------) because(-------blank2-------)

(is zero / points along the vine toward where it's tied / is straight down / is tangent to the circle along which he is going to move / circular motion requires a centripetal acceleration / his initial motion is one of speeding up in a direction tangent to the circle / he hasn't yet started moving / gravity pulls straight down)

part B. Drag words or phrases from each group into the blanks to create a true statement. At the lowest point in Tarzan's swing, his acceleration (-----blank3-----) because( ----blank4-----)

(is zero / points along the vine toward where it's tied / is straight down / is taNgent to the circle in the direction of motion / at about 45 degree above his direction of motion / gravity pulls straight down / he has both centripetal acceleration and tangential acceleration / he has both centripetal acceleration and tangential acceleration / he has a centripetal acceleration but no tangential acceleration / his direction of motion is tangent to the circle / his speed isn't changing at this point)
