Physics

Imagine that at some point during the Ice Age a boulder with amass of 380kg rolls off a cliff and onto a smooth (approximatelyfrictionless) glacier so that just before it hits the glacierits

Ì‚
velocity is ??? = (68m/s)î + (52m/s)k where the z-axis is thepositive vertical direction

(perpendicular to the surface of the earth) and the x-axis isparallel to the surface of the earth.

̂1. (a) (4 points) What is this boulder’s initial momentum (justbefore it hits the glacier) in î, ĵ, k

notation?

Ì‚
(b) (6 points) What is its momentum just after it hits the glacierin î, ĵ, k notation? How do you

know (think about and discuss force directions and conservationof momentum in component form)?
