an automobile travels at a uniform speed of 88 kph. how many metres does it travel in 1 second?

  • physics -

    a man walk 32.5m southward and 78m westward.if it took him 30 minutes to reach his destination.find his average speed?

  • physics -

    88 km/h =88000/3600= 24.44 m/s
    average SPEED = distance/time taken =(32.5+78)/30•60=0.062 m/s
    displacement = sqrt(32.5²+78²)=84.5
    average VELOCITY = displacement/time taken =84.5/30•60=0.047 m/s
