A car is moving with a velocity of 12 m/s [E]. It makes a turn over 8.0 s so that the velocity is 15 m/s [N]. Determine the average acceleration of the car.
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.
3. A car is moving with a velocity of 12 m/s [E]. It makes a turn over 8.0 s so that the velocity is 15 m/s [N].
Determine the average acceleration of the car.
4. A person is standing 15.5 m from a target, which is at a height of 3.10 m. The person wishes to throw a ball
so that it strikes the target. A ball is thrown with an initial velocity directed 40.0° above the horizontal. The ball
is released from a point that is 1.90 m above the ground. What initial velocity is required in order for the ball to
strike the target?
5. A plane is capable of flying 905 km/h without wind. It flies with a heading of [N 22.0° W]. A wind of 65km/h
blows directly East. What is the velocity of the airplane as seen from the ground?
6. A river is 85 meters wide, and has a current speed of 5.0 m/s. A swimmer is capable of swimming at 8.0 m/s
in a pool.
a) If the swimmer pointed directly across the river, how far downstream would they end up after
crossing the river?
b) If the swimmer wished to traverse directly across the river, what angle should they direct their
swim?
