I thought maybe for the part where the trains are travelling in same direction , we should say time to catch the slower train is found by using only speed of faster train and distance apart
For the bicycle problem Vi=10m/s D=780m A= 0.1m/s^2 and T= 60s. I get different final velocities depending on the formula used. For D=1/2(vi+vf)t I get 19.33, but for vf=vi+at and vf^2=Vi^2+2ad I get 16. What am I doing wrong?
I think the answer should be 16 cause Vf for driver 1 is the Vo for 2. So if you just find that then you can calculate for the Vf for driver 2. Then you can just plug everything in the formula Vf = Vo +at, Vf = 10 + 0.1*60, Vf = 16
sir which chapters do i need to know from physics 1 to do physics 2?.. i use the book (physics for scientists and engineers with modern physics 8th).. do i need to know all 23 chapters form physics 1 respectively in order to do physics 2 or just a small bunch of it?
