    How Far Should the Opposite Vehicle Be to Safely Overtake the Truck?

    I see, so there are two velocities to use in the one equation, not separate and the other is car excluded from the question. Is its velocity used later or not at all? Thanks.

    How Far Should the Opposite Vehicle Be to Safely Overtake the Truck?

    Thanks for the reply. I am not sure what equation to use since I am only given velocities, is there any other I am missing because I need another value besides velocity to calculate time. I was thinking t=d/v but I do not have distance unless I use the 50m apart that I need between me and the...

    How Far Should the Opposite Vehicle Be to Safely Overtake the Truck?

    Homework Statement You are on the highway traveling at 110 Km / Hr and are trying to overtake a big truck in front of you (travelling at 100Km/hr). From the opposite direction at 100Km/hour, another car is coming. Assume that you need 50 metres to overtake the truck. Approximately how far...

    How Do You Calculate Braking Distance Based on Initial Speed and Time?

    Thanks for settling the second question but I am still unsure which equation would be best since there is no final velocity and no acceleration.

    How Do You Calculate Braking Distance Based on Initial Speed and Time?

    Homework Statement 1. How much distance does a car cover during this period: from 60 Km/Hr, a car comes to a dead stop in 10 seconds, from the time the brake is applied (answer in m/s) 2. What will be the braking distance if the car travels at 90Km/hour (answer in m/s) Homework Equations...

    Simple Distance to Time Equation

    I know that s = ut + 0.5at^2 is a simple equation to find distance. Assuming that initial velocity does not equal zero, how do you find what time equals since my knowledge of quadratics does not seem to be helping.
