Answer:
Explanation:
The acceleration of an object is given by:
where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the rocket in this problem,
u = 20,000 m/s
v = 24,000 m/s
t = 55.0 - 5.0 = 50.0 s
Substituting,
Because while they’re blind, they still have eyes. Which implies that they had eyes for a reason.
Critical damping is where there is no oscillations or overshoot but the thing is not overdamped. there's a quadratic in the equation somewhere which may help find r.
