Question

cosmonaut Andrei, your co-worker at the International Space Station, tosses a banana at you at a speed of 13 m/s. At exactly the same instant, you fling a scoop of ice cream at Andrei along exactly the same path. The collision between banana and ice cream produces a banana split 8.6 m from your location 1.4 s after the banana and ice cream were launched.

cosmonaut Andrei, your co-worker at the International Space Station, tosses a banana at you at a speed of 13 m/s. At exactly the same instant, you fling a scoop of ice cream at Andrei along exactly the same path. The collision between banana and ice cream produces a banana split 8.6 m from your location 1.4 s after the banana and ice cream were launched. How fast did you toss the ice cream?

Explanation / Answer

ice cream travelled 7.3 meters in 1.3 seconds (7.3 divide by 1.3)
5.62 m/s

Banana velocity is 18 m/s and its time of flight is 1.3seconds (1.3 * 18)
= 23.4 meters
so banana travelled 23.4 meters from Andrei, and Icecream travelled 7.3 meters from you
total distance = 30.7 meters
