Answer:
sum of all forces on the air plane must be ZERO
So both forces must be of same magnitude
Explanation:
As we know that airplane is moving with uniform speed is horizontal plane is a straight line
so the motion of the air plane is uniform without any acceleration
So we will have
acceleration must be zero
now by Newton's law
so sum of all forces on the air plane must be ZERO
Answer:
90 meters
Explanation:
To find the distance in which Bob catches up with Wendy, you first write down the motion equations of both Bob and Wendy.
Wendy has a constant speed, then you have:
(1)
Bob has an accelerated motion, then, his equation of motion is:
(2)
v1: constant speed of Wendy = 3.00 m/s
v2: initial speed of Bob = 0 m/s
a: acceleration of Bob = 0.200m/s^2
When Bob catches up with Wendy x1 = x2, then you equal both equations and solve for time t:
you replace the values of a and v1:
Finally, you replace this value of time either the equation for x1 or the equation for x2, and you calculate the distance:
hence, Bob catches up with Wendy for a distance of 90m
