Question

1. what is the acceleration of a hamster when it increases its velocity from rest to 16 m/s in 1.2 minutes (assume its acceleration is constant)?

Explanation:

Step1: Convert time to seconds

1.2 minutes = 1.2×60 s = 72 s

Step2: Use acceleration formula

The acceleration formula is $a=\frac{v - u}{t}$, where $u = 0$ m/s (starts from rest), $v=16$ m/s and $t = 72$ s. So $a=\frac{16 - 0}{72}=\frac{16}{72}=\frac{2}{9}\approx0.22$ m/s²

Answer:

$\frac{2}{9}$ m/s² or approximately 0.22 m/s²
