Question

If a car changes speed from 50 m/s to 65 m/s in 30 seconds, its average acceleration is?

Answer 1

Given :-

If  a car changes speed from 50 m/s to 65 m/s in 30 seconds

To Find :-

Acceleration

Solution :-

We know that

a = v - u/t

a = 65 - 50/30

a = 15/30

a = 1/2 ms⁻²

Hence

Acceleration is 0.5 m/s²

Answer 2

Answer:

$\mathfrak{\red{Given }:}$

$initial velocity (u)=50 ms^{-1} \\final velocity(v)=65ms^{-1} \\ \\time\:taken\:for\:the\:change=30 seconds\\average acceleration=\frac{5}{30}$
