A. An airplane requires a speed of 80 km/h to take off from a runway. The plane starts from the rest position and undergoes an average acceleration of 1,5 m/s2 [E]. If t plane is taxiing on a 250 m runway, will it have a high enough speed
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

B. A swimmer can swim at a speed of 1.80 m/s in calm water. If the current
of a 200 m wide river runs at 1.00 m/s [E] and if the swimmer starts from the
south bank and swim always heading perpendicular to the bank,
determines the resulting speed vector of the swimmer relative to the bank
from the river. Justify your answer using calculations.
C. A skier descends a slope which makes an angle O with the horizontal. If µ is
the coefficient of friction between the skis and the snow, demonstrates that the acceleration,
a=g (sin 0 - µ cos 0 ). It would be important to make a diagram of forces.) **You do not need
