Question

Sketch a velocity - time graph on the axes provided for

1. an object thrown vertically upwards up to maximum height with initial velocity μ         ms^-1 and takes 5 seconds to reach maximum height.        
   
2. An object moving at constant acceleration from rest.         
   
3. A ball is thrown horizontally from the edge of a cliff at a velocity of 10ms⁻¹ and hits the ground below after 10 seconds. Determine the height of the cliff.    

Answer 1

1. Answer
   
2. Answer
   
3.  h=½gt²
     =½×10ms⁻²×10×10
     =500m
