1).A car accelerates from rest until it is traveling at 88km/hr. The time to keep up to speed is 6.2 sec. What is the acceleration of the car in m/s2 ? How far t=did the car travel in 6.2 secs in meters?
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.

2). A rock is dropped from rest and free falss at 10m/s. How fast will the rock be moving right before it hits the ground it it falls 3.3m? HOw long dies it take for the rock to fall 3.3m?
3). A rock is thrown upwar and reached a height of 12m. How fast was the rock thrown? How long does it take for the rock to reach its max height?
4) A family road trip starts out in a van travelling 50km at a velocity of 75km/ hr followed by a spot of slow traffic where they travel 10km at a velocity of 25km/hr. What is the average velocity during the trip km/hr?
5) A car moves with velocity of 60km/hr for 45 min. The driver takes a 15min break at a gas station before travelling at 70kmm/hr for 30min. What was the average velocity of the car over the total trip in km/hr?
