The model airplain has mass of 0.9Kg and moves at a constant
Speed on a
cicle that is parallel
the ground The path of the airplane
and its guideline lies in
the same
horizontal plane because the weight of
the plane is
balanced by the lift generated
by wings.
Find the tension is in the
guideline (the length of the guideline 17m)
for
speed of
19m/s and 38m/s​

In what direction does an applied force move an object? in the same direction as the force independent of the force in the opposite direction of the force perpendicular to the force

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
