In physical science, there are two types of quantity: scalar and vector. While scalar quantities only include the magnitude, vector quantities include both the magnitude and the direction. Displacement is an example of vector quantities. Therefore, it includes magnitude and direction.

Answer: 4m/s²
Explanation:
At stop signal car speed iz 0 ; V1=0m/s
After t=5s , car has speed is V2=20m/s
using:
a=(V2-V1)/t
a=(20m/s-0m/s)/5s
a=20m/s/5s
a=4m/s²
Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
