Question

You throw a ball straight up in the air at a speed of 19.6 m/s. Assume there is no air resistance. Make a table (include time and speed) showing the ball's speed each second for 4 seconds.__________

Answer 1

To create a table showing the ball's speed each second for 4 seconds, we can use the equation for the ball's upward velocity. The initial speed of the ball is 19.6 m/s, and the acceleration due to gravity is -9.8 m/s².

Step-by-step explanation:

To create a table showing the ball's speed each second for 4 seconds, we can use the equation for the ball's upward velocity. The initial speed of the ball is 19.6 m/s, and the acceleration due to gravity is -9.8 m/s² (negative because it acts downward).

1. At t = 0 seconds, the ball's speed is 19.6 m/s
2. At t = 1 second, we use the equation v = v0 + a*t to find v = 19.6 + (-9.8 * 1) = 9.8 m/s
3. At t = 2 seconds, v = 19.6 + (-9.8 * 2) = 0 m/s
4. At t = 3 seconds, v = 19.6 + (-9.8 * 3) = -9.8 m/s
5. At t = 4 seconds, v = 19.6 + (-9.8 * 4) = -19.6 m/s

So the table for the ball's speed each second for 4 seconds would look like:
