TMot51 A dog can jump to a height of 0.6 m.
What is the initial velocity of the dog and how long is it in the air?
Diagram the situation.
Be careful of the signs! If the dog jumps up with a positive velocity it reaches maximum height while under a negative (down) acceleration.
To find the time use
The dog leaves the ground with velocity 3.4 m/s and is in the air 0.68 s (up and down).
