Asmall car weighing 2,876 lbs is traveling due north when it collides with a pick-up truck weighing 10,916 lbs which was traveling due east. after the collision the two vehicles move off together at an angle of 24 degree north of east. the driver of the car claimed that the truck driver was at fault because he was exceeding the speed limit going 69 mph.

if this were true, what was the car's initial velocity?

it was determined from skid marks that the velocity of the combined system was 31 mph just after the collision. what was the actual velocity of the car?

what was the actual velocity of the truck?

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

technology is the application of the knowledge gained by science.
