Answer 1

Explanation:

____heya mate ___

☆☆here is your answer ☆☆

Intial Velocity = u = 200km/hr = 20×5/8

=5.56m/s

Final velocity = v=50 km/hr= 50 ×5/18 =13.89m/s

Time = T = 10 sec

Acceleration =a

A= (v-u) /t

= (13.89-5.56) /10

Ans = 0.833m/s ( square)

hope this answer and method will help you!!!

Answer 2

Answer:

$\huge\boxed{\underline{\underline{\purple{hello}}}}$

ANSWER =2m/s²

Explanation:

Given =v=m/s,u=20km/a

to convert km/s into m/a multiply by 5/8

The formula of acceleration is ⤵️

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

$a = \frac{13.89 - 5.56}{10}$

$a = 0.833m{s}^{2}$

the ACCELERATION is 0.833m/s²
