Clair throws a softball 7.2 m east to Sasha, who then throws it 9.5 m west back to Clair who had to move back to catch the ball. The time takes 6.0s.
Calculate: the velocity
To calculate the velocity, we need to find the total displacement and divide it by the total time.
First, let's find the total displacement.
Clair throws the ball 7.2 m east.
Sasha throws the ball 9.5 m west.
Since Clair moves back to catch the ball, her displacement will be negative.
Therefore, the total displacement is 7.2 m - 9.5 m = -2.3 m.
Now, let's calculate the velocity.
Velocity is defined as displacement divided by time.
V = Δx ÷ Δt
V = -2.3 m ÷ 6.0 s
Calculating the velocity:
V = -0.383 m/s
Therefore, the velocity of the ball is -0.383 m/s.
