Options:
1.Case
C2.It will be the same in all three cases.
3.Case A
4.Case B
Answer:C2. It will be the same in all three cases.
Explanation:In the above scenerio,
F, is the only net force that is acting on the System. Hence, the acceleration of the center of mass (a point in an object where a force can be applied to cause a linear acceleration without leading to an angular acceleration)is the same in each of the cases highlighted.The torque(the rotational equivalent of a linear force) depends on where the force acts.
Explanation:
this is how I understand it!!
The final velocity of the airplane is 7.2 m/s
Explanation:
The motion of the airplane is a uniformly accelerated motion, (constant acceleration), therefore we can use the suvat equation
v = u + at
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
In this problem, we have
u = 6 m/s is the initial velocity
is the acceleration
t = 4 s is the time elapsed
Substituting the values, we find the velocity after 4 seconds:
