If a ball of mass 5kg is dropped from rest, how far will it travel in the 3 seconds after it reaches 150m from it's original position? Write down the change in it's total energy after the 3 seconds. (ignoring air resistance)
- Calculate the speed the ball is travelling at when it reaches 150m using v2 = u2 + 2ax. 2) Calculate the distance travelled in 3 seconds by an object with a speed of that found in 1) and an acceleration of g using x = ut + (1/2)at2. Final answer = 207m Change in total energy = 0J
