Question:

Starting from rest a particle confined to move along a straight line is accelerated at a rate of 4m/s(squared). After 10 seconds how far will the particle have traveled?

Answer:

Distance for uniformly accelerated motion can be expressed as:

$$s = \frac {a t ^ {2}}{2}$$

where $t$ is time, $a$ is acceleration.

$$s = \frac {a t ^ {2}}{2} = \frac {4 \cdot 10 ^ {2}}{2} = 200 \, \text{m}$$

Answer: 200 m
