Answer
a = 3.674 m / s ^ 2
t = 3.13 s
Using the kinematic equations for the movement we have:
(1)
(2)
Where:
= initial position
= initial velocity
a = acceleration
t = time in seconds
= final speed
We know:
h = 18 m
So:
From (2) we have that:
From (1) we have to:
Then we clear "a" to find the acceleration.
Then, the time it takes to reach this speed is:
Answer:
-22.2 m/s²
Explanation:
The equation for position x for a constant acceleration a, time t and initial velocity v₀, initial position x₀:
(1)
For rocket A the initial and final position: x = x₀= 0. Using these values in equation 1 gives:
(2)
Solving for time t:
(3)
The times for both rockets must be equal, since they start and end at the same location. Using equation 3 for rocket A and B gives:
(4)
Solving equation 4 for acceleration of rocket B:
(5)
