a) Write equations for distance from the light vs time for bike and car. Call them X1(t) and X2(t) Set X1 = X2 and solve for t. These are piecewise continous functions, so you cannot solve single equations. If t is in seconds and X in feet, X1(car) = 5.94 t^2 Car acceleration ...

A more complete explanation... The car is traveling horizontally at a constant speed. When it drives off the cliff, it keeps going at the same speed (disregarding friction) until it is stopped by hitting the ground. A forumla for (d) distance traveled with constant ...

Physics - Momentum of cars at intersection
Two cars of identical mass are approaching the same intersection, one from the south and the one from the west. They reach the intersection at the same time and collide. The cars lock together and move away at an angle of 22deg counterclockwise from the road; heading east. ...

A car is traveling around a horizontal circular track with radius r = 240 m at a constant speed v = 25 m/s as shown. The angle èA = 34° above the x axis, and the angle èB = 65° below the x axis. I found the car's acceleration to be 2.6 m/s^2 (a=v^2/r). Now I need to know the x...
