Question

A slug traveling at 3 mm/h north decided to race the slug next to him by increasing his own velocity to 5 mm/h north over the course of one hour. What was the slug’s acceleration?

Answer 1

Answer:

The acceleration of the slug is $2\frac{mm}{hr^{2} }$.

Explanation:

Initial velocity(u) = 3 mm/h.

Final velocity(v) = 5 mm/h.

Time taken(t) = 1 hour.

Acceleration(a) = $\frac{(v-u)}{t}$

$a = \frac{5 - 3}{1}$ = $2\frac{mm}{hr^{2} }$.
