Question:

A car starts from rest and travels in a straight line with a constant acceleration of 2 m/s^2. After 5 seconds, what is the displacement of the car?

Answer:

To find the displacement of the car, we can use the equation:

Where:

• $s$ = displacement
• $u$ = initial velocity (in this case, the car starts from rest, so $u = 0$)
• $a$ = acceleration
• $t$ = time

Plugging in the given values:

• $u = 0$
• $a = 2 \, m/s^2$
• $t = 5 \, s$

We get:

Therefore, after 5 seconds, the displacement of the car is 25 meters.
