Question

Joe accelerates his skateboard uniformly along a straight path from rest to 8 m/s over the span of 3.5 seconds. What is Joe’s acceleration?

A. 2.29 m/s²
B. 2.86 m/s²
C. 3.14 m/s²
D. 3.71 m/s²

Answer 1

Joe's acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substituting the given values, Joe's acceleration is 2.29 m/s².

Step-by-step explanation:

To find Joe's acceleration, we can use the formula: acceleration = (final velocity - initial velocity) / time.

Given that Joe accelerates from rest (0 m/s) to 8 m/s over a span of 3.5 seconds, we can substitute these values into the formula to calculate the acceleration: acceleration = (8 m/s - 0 m/s) / 3.5 s = 2.29 m/s².

Therefore, Joe's acceleration is 2.29 m/s² (Option A).
