Sled Acceleration Distance
1. **State the problem:** A rocket-powered sled accelerates from rest to a speed of 444 m/s in 1.83 seconds. We need to find the distance traveled during this acceleration.
2. **Identify known values:**
- Initial velocity, $v_0 = 0$ m/s (starting from rest)
- Final velocity, $v = 444$ m/s
- Time, $t = 1.83$ s
3. **Calculate acceleration using the formula:**
$$a = \frac{v - v_0}{t} = \frac{444 - 0}{1.83} = 242.62\ \text{m/s}^2$$
4. **Calculate distance traveled using the formula for uniformly accelerated motion:**
$$s = v_0 t + \frac{1}{2} a t^2 = 0 \times 1.83 + \frac{1}{2} (242.62)(1.83)^2$$
5. **Simplify:**
$$s = \frac{1}{2} (242.62)(3.3489) = 121.31 \times 3.3489 = 405.88 \ \text{meters}$$
6. **Final answer:** The sled travels approximately **406 meters** during the acceleration.
