Obtaining the component part of the letter 'i' warns that it is the velocity is oriented on the X axis. At the same time the numeric part, in this particular case will represent the scalar part and therefore the magnitude of the vector.
The velocity is

The vector component of the velocity is

The scalar component of the velocity is

The magnitude of the velocity is

Answer:
t=0.016s
Explanation:
we can use

the time that the particle is in the magnetic field is one half oa period. Hence

Answer:
because there is many places for it to bounce of of creating another soundwave
So, the acceleration of the bicycle is approximately <u>-1.67 m/s²</u> or it can be said to be decelerating approximately <u>1.67 m/s²</u>.
<h3>Introduction</h3>
Hi ! Here I will help material about linear motion changes regularly, which is where you will hear a lot of the term acceleration. Acceleration occurs when an object's speed increases in a certain time interval. Acceleration can be negative which is called deceleration. The relationship between acceleration with velocity and time is manifested in the equation:

With the following conditions :
- a = acceleration (m/s²)
= object's final velocity (m/s)
= object's initial velocity (m/s)- t = interval of the time (s)
<h3>Problem Solving </h3>
We know that :
= object's final velocity = 4 m/s
= object's initial velocity = 12 m/s- t = interval of the time = 4.8 s
What was asked :
- a = acceleration = ... m/s²
Step by step :




So, the acceleration of the bicycle is about -1.67 m/s² or it can be said to be decelerating around 1.67 m/s².
