Question

0.6 Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is
accelerated to a speed of 444m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?​

Answer 1

Explanation:

v=444m/s t=1.8s

$a = \frac{v - u}{t} = \frac{444 - 0}{1.8} = 246.67m {s}^{ - 2}$

distance travelled,s

$s = ut + \frac{1}{2} a {t}^{2} \\ s = 0 \times 1.8 + \frac{1}{2} \times 246.67 \times {1.8}^{2} \\ s = 399.60m$

Answer 2

Answer:

v=444m/s t=1.8s

a = \frac{v - u}{t} = \frac{444 - 0}{1.8} = 246.67m {s}^{ - 2}

distance travelled,s

s = ut + \frac{1}{2} a {t}^{2} \\ s = 0 \times 1.8 + \frac{1}{2} \times 246.67 \times {1.8}^{2} \\ s = 399.60m
