Answer:
The acceleration of this helicopter is [tex]2 m/s2[/tex]
Explanation:
In this question the velocity changes from 30 m/sto 40 m/s in 5 seconds.
Initial velocity u= [tex]30m/s[/tex]
Final velocity u= [tex]40m/s[/tex]
Time t= [tex]5s[/tex]
Acceleration is defined as the rate of change of velocity. It is given by the equation
[tex]a= \frac{v-u}{t}[/tex]
=[tex]\frac{40-30}{5}[/tex]
= [tex]\frac{10}{5}[/tex]
= [tex]2 m/s2[/tex]
All moving bodies aren’t necessarily accelerated. To be identified as accelerating, a body should have its velocity changing. Thus a body in uniform motion is not accelerating since its velocity is constant.
Answer:
A helicopter’s speed increases from 30 m/s to 40 m/s in 5 seconds.
