A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial vertically downward velocity of 1.40 m/s and observes that it takes 1.80 s to reach the water. How high above the water was the preserver released?
What is the initial vertically upward speed of the kangaroo that jumps over the object?
How much time is the kangaroo in the air for during its jump over the object?
How far does the object fall on Earth?
How far does the object fall on the Moon, where the acceleration due to gravity is one sixth of that on Earth?
