Question

Find Sam’s acceleration between 12 and 40 seconds.

a) 3m/s ²

b) 4m/s ²

c) 5m/s ²

d) 6m/s ²

Answer 1

Sam's acceleration between 12 and 40 seconds is 0.0357 m/s².

Step-by-step explanation:

To find Sam's acceleration between 12 and 40 seconds, we need to use the formula:
a = (vf - vi) / t
where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time. Given that vf = 12.2 m/s and vi = 11.2 m/s, we can calculate the acceleration as:
a = (12.2 - 11.2) / (40 - 12)
a = 1 / 28
a = 0.0357 m/s²
