Using equation of motion with
constant acceleration we can easily plot velocity -time as well as
distance time graph . Calculation and graph is shown below.

f A model rocket is fired vertically upward from rest. Its acceleration for the first three seconds is atet) sat, at which time the fuel is exhausted and it becomes a nds later, the rocket's parachute opens, and the (downward) velocity slows inearty to-13 n/s in S s. The rocket then "hets" to the ground at that rate freely "Talling" body. Thirteer (a) Determine the position function s and the velocity function v (for all...

1. A rocket accelerates upward from rest during the first stage with a constant acceleration of a1 = 95.0 m/s2 for t1 = 30.0 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 50.0 m/s2 for t2 = 60.0 s. (a) What is the total distance traveled by the rocket during both stages? (b) What is the speed of the rocket after the second stage burn?
6. Two rockets start from rest at the same elevation. Rocket A accelerates vertically at 20 m/s for 12 s and then maintains a constant speed. Rocket B accelerates at 10 m/s2 until reaching a constant speed of 150 m/s a. Construct the a-t, v-t, and s-t graphs for each rocket until t20 s b. What is the distance between the rockets when t 20 s?

39. Rocket Motion Suppose a small single-stage rocket of total mass m) is launched vertically, the positive direction is upward, the air resistance is linear, and the rocket consumes its fuel at a constant rate. In Problem 22 of Exercises 1.3 you were asked to use Newton's second law of motion in the form given in (17) of that exercise set to show that a mathematical model for the velocity v(t) of the rocket is given...
A rocket rises vertically, from rest, with an acceleration of 3.2 m/s2 until it runs out of fuel at an altitude of 1300 m. After this point, its acceleration is that of gravity, downward. (a) What is the velocity of the rocket when it runs out of fuel? (Assume up is positive.) 1 m/s (b) How long does it take to reach this point? 2 s (c) What maximum altitude does the rocket reach? 3 m (d) How much time...
A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.60 m/s2 .At 30.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. What is the height of the rocket when the engine fails? Find the magnitudes of the rocket's velocity and acceleration at its highest point. How long after it was launched will the rocket fall back to the launch pad?
