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>s 2 ) 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?

Reading Graphs: Impulse J = Force x change in time p = mv Only next impulse equals change in momentum These quantities are vectors The impulse of the graph can be determined by: the area under a Force vs Time F(t) graph Why It’s Important o Force plates are commonly used to study a variety of things Biomechanics,...
