A projectile is propelled along the x-axis. During 5.2 s it moves from position 64 m to position −40 m. Find its average velocity.
moves negative 104 meter in 5.2 seconds
v = -104/5.2 meters/second
To find the average velocity of a projectile, we need to divide the change in position by the time it took to undergo that change. In this case, the change in position is given as 64 m to -40 m, which means a displacement of (-40) - 64 = -104 m.
We are also given the time it took for this displacement, which is 5.2 s.
Therefore, the average velocity can be calculated as:
Average Velocity = Displacement / Time
Average Velocity = (-104 m) / (5.2 s)
Now we can solve for the average velocity:
Average Velocity = -104 m / 5.2 s
Average Velocity ≈ -20 m/s
So, the average velocity of the projectile is approximately -20 m/s along the x-axis.
