Question
Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme acceleration on the human body. On December $10,1954,$ Stapp rode a rocket sled, accelerating from rest to a top speed of $282 \mathrm{m} / \mathrm{s}$ (1015 $\mathrm{km} / \mathrm{h}$ ) in $5.00 \mathrm{s}$ and was brought jarringly back to rest in only 1.40 s. Calculate his (a) acceleration in his direction of motion and (b) acceleration opposite to his direction of motion. Express each in multiples of $g\left(9.80 \mathrm{m} / \mathrm{s}^{2}\right)$ by taking its ratio to the acceleration of gravity.
Step 1
00 \, s$. We can use the first equation of motion to find the acceleration during the accelerating phase: \[v = u + at\] Substituting the given values, we get: \[282 = 0 + a(5.00)\] Solving for $a$, we get $a = 282/5.00 = 56.4 \, m/s^2$. Show more…
