Solve the problem.

4
A ball rolls at an average velocity
of 1.75 m/s for 5.20 s.
What is the displacement of the ball?
Ax= [?] m

Hint: Positive velocities are shown with (+);
Negative velocites are shown with (-)

Answer 1

To calculate the displacement of the ball, multiply the average velocity (1.75 m/s) by the time (5.20 s), resulting in a displacement of 9.10 meters.

Step-by-step explanation:

To find the displacement of the ball, we use the formula for displacement which is the product of average velocity and time when acceleration is constant. Displacement (Δx) can be calculated using the equation:

Δx = v * t

Where:

• v is the average velocity of the ball
• t is the time for which the ball has been rolling

As given:

• v = 1.75 m/s
• t = 5.20 s

By substituting the known values into the formula, we get:

Δx = 1.75 m/s * 5.20 s

Δx = 9.10 m

Therefore, the displacement of the ball is 9.10 meters.
