Problem 29E

At launch a rocket ship weighs 4.5 million pounds. When it is launched from rest, it takes 8.00 s to reach 161 km/h; at the end of the first 1.00 min, its speed is 1610 km/h. (a) What is the average acceleration (in m/s2) of the rocket (i) during the first 8.00 s and (ii) between 8.00 s and the end of the first 1.00 min? (b) Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the rocket travel (i) during the first 8.00 s and (ii) during the interval from 8.00 s to 1.00 min?

Step-by-Step Solution:

Solution 29E Step 1: Given data Mass of the rocket (m) = 4.5 million pounds When time t = 8 s , speed v = 161 km/h t = 1 minute or 60 s , v = 1610 km/h To find average acceleration in m/s 2
