A man is driving his sports car down a four-lane highway at 40 m/s. He comes up behind a slow-moving dump truck and decides to pass it in the left-hand lane. If Nathaniel can accelerate at 5m/s², how long will it take for him to reach the speed of 60 m/s²?
-
If a car, with an initial velocity of 20m/s, accelerates at a rate of 5m/s² for 3 seconds, what will its final velocity be
MOTION IN ONE DIMENTION
a. Speed – refers to how fast the object is moving. It tells you the distance the object travels in a period of time. In symbols,
S = d/t
Where:
S = speed
d = distance
t = time
Lydia de Vega is a world known Filipino track and field athlete. She can run the 100.0 m dash in about 11.0 seconds. What is her average speed?
Given: d=100.0 m
t = 11.0 s
RTF (required to find) = average speed
Solution:
S = d/t
S = 100.0m/11.0s
S = 9.09 m/s

Velocity – aside from identifying the rate of a moving body, we also take into consideration the direction of motion. With this, we use the term velocity.
In equation, we can express velocity as:
v = d/t
Where:
v = velocity
d = displacement (distance + direction)
t = time

Example problem for Velocity:
The car is heading north covering a distance of 500 meters in 20.0 seconds. What is the car’s velocity?
Given: d = 500 m
t = 20 s
RTF (required to find) = v
Solution:
v = d/t
v = 500m/20.0s
v = 25.0 m/s, north

c. Acceleration –
Formula: acceleration = change in velocity
time
In symbols, a = ∆ v where:
t a = acceleration
a = Vf – Vi vf = final velocity
t vi = initial velocity
t = time
