7. Reid runs away from Joharri after an intense political debate. His initial acceleration is
Okm/h and his final acceleration is 25 km/hour in 10 seconds. What is Reid's average
acceleration?


Sagot :

Answer:

0.6944 m/sec^2

Explanation:

The computation of the average acceleration is given below:

a = v - u ÷ t

where

a denotes average acceleration

v denotes final velocity

u denotes initial velocity

t denotes time

So, the average acceleration is

= (25 - 0) ÷ 10

= 0.6944 m/sec^2
