Question

A helicopter’s speed increases from 30 m/s to 40 m/s in 5 seconds.

What is the acceleration of this helicopter?

______ m/s2

Answer 1

Answer:

the answer is

Explanation:

2 m/s²

Explanation:

Acceleration is computed by dividing the change in velocity over the change in time. The formula then is as follows,

\vec{a} = \frac{v_f - v_i}{t_f - t_i}

a

=

t

f

−t

i

v

f

−v

i

Substitute the given values. Take note that initial time is 0 as it is not stated.

\begin{gathered}\vec{a} = \frac{40 - 30}{5 - 0}\\\vec{a} = \frac{10}{5}\\\vec{a} = 2\end{gathered}

a

=

5−0

40−30

a

=

5

10

a

=2

Therefore, the acceleration is 2 m/s²
