1. The problem statement, all variables and given/known data Just when a Frisbee passes over the head of a student at a speed of 4m/s and decelerating at a rate of 1.5 m/s2, she starts to run accelerating at a rate of 1 m/s2. [neglect vertical motion of Frisbee] a)How long will it take the student to catch the Frisbee? b) If instead of accelerating the student were able to run at a constant speed of 2 m/s as soon as the Frisbee passes her head how far would she have to run to catch it? 2. Relevant equations x=x0+V0t+1/2at2 3. The attempt at a solution So for part a, I figured if I made both xfrisbee and xstudent equal to each other I could solve for t xfrisbee=0+4t+(0.5)(-1.5)t2 xstudent=0+0t+(0.5)(1)t2 0.5t2=4t+0.75t2 t=0s t=3.2s And something similar for part b: xfrisbee=0+4t+(0.5)(-1.5)t2 xstudent=0+2t+(0.5)(0)t2 4t+(0.5)(-1.5)t2=2t t=0s t=2.7s x=(2m/s)(2.7s)=5.4m I just wanted to know if I got these right. Thanks!
