At a drag race, the light turns green and 0.00125 hours later, a dragster is travelling 300 miles per hour. calculate the acceleration of the dragster

The acceleration of the dragster is 29.80m/s²

Explanation:

Acceleration is defined as the change in velocity of a body with respect to time.

Acceleration = Change in velocity/Time

Given the velocity = 300miles/hour

Time = 0.00125hours

Converting the time to seconds and velocity to meter/seconds

Since 1hour = 3600seconds

Time = 0.00125×3600

Time = 4.5seconds.

For velocity:

1hour = 3600seconds

1mile = 1609.343m

300miles/hour = (300×1609.343m)/1×3600sec

= 482,803.2m/3600secs

= 134.112m/s

Acceleration in m/s² = 134.112/4.5

Acceleration = 29.80m/s²

  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.
