Question

The food package dropped from a helicopter arrives with 5s. What is its acceleration if its velocity is 5 / ms before it touches the ground. ​Please answer quickly

Answer 1

Explanation:

Initial velocity, u = 5 m/s

Final velocity,v = o m/s

Time= 5 sec

From v = u +at

a = v-u/t

a= o-5/5

= -5/5= -1 m/s square

Answer 2

$u = 5 \: ms {}^{ - 1}$

$v = 0$

$t = 5 \: s$

Using Formula

$\large{a = \frac{v - u}{t}}$

$\large{a = \frac{0 - 5}{5}}$

$\large{a = \frac{ - 5}{5}}$

$\huge\green{ \boxed{\pink{ a = - 1 \: ms {}^{ - 2}}}}$
