In particular, Nate would cften don a protective suit of Bounce-Tex, which he invented, and after working up a high speed on his skateboard, would colide with some object. In this way, he got a gut feel for the occasion, the his two passions."On one properties of collisions and succeeded in with a mass of 115 kg. indluding his amor. huried himself against a 893- kg stationary statue of Isaac Newion in a perfectly elastic inear collision. As a resut, isaac started maving at 1.71 ms and Nate bounced backward. What were Nate's speeds immediately before and after the colision? (Enter positive numbers.) Ignore friction with the ground Before: Number m/s After m/s he way, this brief bio of Nate the Skate is writen in the past tense, because not i perfecly he forgot to collisión.

[ Taster lab2 Restrictio.. pf Taster lah2 Restrictio · Linden iron-on.pdfExplanation / Answer
according to law of c0nservation of linear momentum m1u1+m2u2=m1v1+m2v2............1
and relative velocity ofbefore collision=relative velocity after collision i.e u1-u2=v2-v1...............2
here u1=?,u2=0,v1=?v2=1.71 and m1=massof skate =115kg,m2=mass of statue=893kg
from 2............ u1-0=1.71-v1 this is substitute in equation 1 then
115*(1.71-v1)+0=115v1+893*1.71
v1=-133038/230=-5.78m/s then u1=1.71-(-5.78)=7.49m/s
before collision nate speed u1=7.49m/s
after collision nate speed v1=-5.78m/s
