Question

1 select the correct answer. what is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a velocity of 30 meters/second? a. 1.6 meters/second² b. 3.0 meters/second² c. 3.4 meters/second² d. 5.0 meters/second² reset next

Explanation:

Answer:

D. 5.0 meters/second²

(Explanation: Acceleration \( a = \frac{\Delta v}{\Delta t} = \frac{30 - 20}{2.0} = 5.0 \, \text{m/s}^2 \))
