Answer 1

Answer:

12m/s2

Explanation:

Answer 2

Answer:

If it helps mark me as brainliest.

Explanation:

Given, initial velocity,u = 100 km/hr = 250/9 m/s

Final velocity, v= 60 km/hr = 150/9 m/s

Therefore,

acceleration

= (v-u)/t

= {(150/9 - 250/9)/ 7 m/s}^2

= - 100/63 m/s^2

= -1.58 m/s^2
