Can’t top the first answer so check that out. My boy is a legend.
I would say C but I’m not complete sore
Answer:
a = - 11.53[m/s^2]
Explanation:
The airplane slows down as its speed decreases from the initial value of 610 [m/s] to zero.
To calculate the acceleration value we use the following kinematics equation:
where:
Vf = final velocity = 0
Vi = initial velocity = 610 [m/s]
a = acceleration [m/s2]
t = time = 53 [s]
Now replacing:
0 = 610 + (a*53)
-610 = 53*a
a = - 11.53[m/s^2]
The negative sign means that the aircraft is losing speed, i.e. slowing down
Answer:
The correct option is B
Explanation:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion. A common physics demonstration relies on this principle that the more massive the object, the more that object resist changes in its state of motion.
Answer:
21.6 kN
Explanation:
F = m * a
F = 54 000 * .4 = 21600 N
