Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds,

then what is the acceleration and what is the distance that the sled travels?


U = 0
v = 444 m/s
t = 1.83 s

acceleration= \frac{v-u}{t}= \frac{444-0}{1.83}=242.6\ m/s^2

distance=ut+ \frac{1}{2}at^2=0 \times 1.83+ \frac{1}{2} \times 242.6 \times 1.83^2=406.3\ m
