Explanation:
Ride in a car down the street: constant velocity,
come to a red light: negative acceleration,
wait for the green light: zero velocity,
<span>start off again: </span>positive acceleration
Answer:
Any object that is being acted upon only by the force of gravity is said to be in a state of free fall.
Explanation:
Answer: 15.87 m
From the equation of motion:
where, 
is the distance traveled, 
is the initial velocity, 
is the acceleration and 
is the time.
The rock free falls under gravity. Initial velocity, 
, 
It took 
for rock to hit the water.
Substitute the values in the given equation:
Hence, the water is 15.87 m below the top level of the well.
<h3>Speed between point A and B</h3>
= Total Distance/Total time
= 30/3
= 10 km/h
<h3>Average speed for this ride</h3>
Average speed = Total distance travelled/time taken
= 50/6
= 8.3 km/h
