Problem

Relative to the ground, a drone moves in one dimension with velocity

v(t)=2.0t+1.0\,\text{m/s}

, where

t

is measured in seconds. A car travels in the same direction at a constant

5.0\,\text{m/s}

and is momentarily next to the drone at

t=0

. What acceleration does a passenger in the car assign to the drone? (a)

1.0\,\text{m/s}^2

(b)

2.0\,\text{m/s}^2

(c)

0\,\text{m/s}^2

(d)

3.0\,\text{m/s}^2
