Question

select the correct answer. in a video game, a ball moving at 0.6 meters/second collides with a wall. after the collision, the velocity of the ball changed to -0.4 meters/second. the collision takes 0.2 seconds to occur. whats the acceleration of the ball during the collision? use a = \\(\frac{v - u}{t}\\). a. -1.0 m/s² b. 1.0 m/s² c. -5.0 m/s² d. 5.0 m/s² e. 0.24 m/s²

Explanation:

Step1: Identify variables

\( u = 0.6 \, \text{m/s}, v = -0.4 \, \text{m/s}, t = 0.2 \, \text{s} \)

Step2: Calculate velocity change

\( v - u = -0.4 - 0.6 = -1.0 \, \text{m/s} \)

Step3: Compute acceleration

\( a = \frac{-1.0}{0.2} = -5.0 \, \text{m/s}^2 \)

Answer:

C. -5.0 m/s²
