Next problem: How high will the arrow be 7 seconds after being shot up at 50m/s? Answer: 105m.
What is increase in speed per second?
Average Acceleration Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second.
How long until the arrow hits the ground?
At the moment the arrow hits the ground with its final velocity, it takes 0.025 seconds for the arrow to come to a complete stop in the ground. What is the acceleration of the arrow? An arrow is shot from an initial height of 350 meters, 40 degrees above horizontal with and initial velocity of 70 m/s.

Why is speed per second per second?
Per second per second is defined as that the speed something is moving is increasing so many meters per second in every second.
How do arrows go straight?
Every arrow in flight has two nodes, one near the back and one near the front. Nodes are points on the shaft that remain in the same place while everything else bends. A line between these two nodes is the straight line that points where the arrow is heading. Straighter than an arrow, you might say!
How far does an arrow drop?
