A police car is chasing a stolen car ahead of it. If the police car is traveling at 150 km/h (N) and the stolen car is traveling at 120 km/h (N), then determine:
a) velocity of police car relative to ground b) vel. to the pol. car relative to the stol. car c) vel of stol car relative to the pol. car. 2. oVe= oVm+ mVe
3. I'm confused about relative motion or just motion in general, but this is what I came up with:
pVe=150 and sVe=120 (e being earth)
So, A=150km/h B) pve=pvs+sve which when you plug in you get pvs=30km/h (I'm assuming the positive answers mean the direction is North?? and C) sVp = -pVs= -30km/h ...but that doesn't make sense...direction would be South?
I'm confused, can someone please explain?
