Subscribe RSSTwo go karts are racing,Kart XJ moves with a speed of 20mph,when kart ZX is moving at 30mph and about to?
Q: overtake kart XJ,however kart XJ then accelerates at a constant of 0.25mph each second until it passes ZX. How long will ZX be ahead XJ?
Been having trouble solving this one,please show in as detailed as possible. Thankx for the help everyone.
A: So the initial relative position is zero.
The initial relative velocity (v0) is 10 mph
The constant acceleration (a) is 0.25 mph / second
This is just like throwing a ball straight up and down from the ground. The numbers and units are just a bit different.

given that at t=0 both have the same position, with ZX moving at 30 mph and XJ moving at 20 mph. ZX passes XJ the instant that XJ begins to accelerate. The solution is when they are at...
