Question

· When a body moving with a speed of
20 m/s. stops in 20 seconds, what is the
acceleration?​

Answer 1

Answer:

given:- u = 20 m/s

v = 0 m/s

t = 20 s

to find:- acceleration

solution:- a = v-u / t

= 0 - 20/20

= -20/20

= -1 m/ s square

plz follow me!!!!

Answer 2

Answer:

given that u=20 and v=1000 to find the acceleration is v-u/t

20-1000/20

= 1980/20

= 99m/s square is the answer
