Tom drops his pliers from the top of the Montreal Tower in Canada while repairing an electrical circuit. The tower is 574 feet high. He wonders what the speed of the pliers will be after 1 second. He also wonders itis speed when it hits the ground.

What is known:

  • The height of the tower is 574 feet.
  • Height as a function of time is: s = 16t2
    Questions


s = 16t2

 
  • What is the velocity of the pliers after they drop for 1 second?
  • What is the velocity of the pliers when it reaches the ground?
  Approach

 

The velocity at a specific point or time is the slope of its distance verse time curve.
