(400) Problem 3: A rocket accelerates upward from rest, due to the first stage, with a constant acceleration of a 93 m/s for ti 29 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a-41 m/s for the time interval t2-55 s acceleration two acceleration one Otheexpertta.com 33% Part (a) Enter an expression for the rocket's speed. v1. at time t1 1n terms of the variables provided. 33% Part (b) Enter an expression for the rocket's speed, v2, at the end of the second period of acceleration in terms of the variables provided in the problem statement 33% Part (c) Using vour expressions for speeds v1 and v2. calculate the total distance traveled in meters by the rocket from launch until the end of the second period of acceleration Grade Summary Deductions Potential 100% 0%Explanation / Answer
a) V0= 0 m/s
t1= 29 sec
a1 =93m/sec2
V1 = V0+at1 = 0+93*29 =2697m/sec
b) t2=55sec
a2 =41 m/sec2
V2 = V1+a2*t2 = 2697 +41*55 = 4952m/sec
c) d1 =V0.t1 +0.5*a1*t12 = 39106.5m
d2 = V1*t2 + 0.5*a2*t22 = 210347.5m
d = d1+d2 =249454m
