Answer:

b 2ms-¹ put this 2 and value of k in the given equation and it becomes zero then it is 2ms-¹

Answer 2

Explanation:

Answer :- 8 m/s.

bro this question is easy...

now, first see what is given in your question.

...given :-

u = 0 m/s

a = 0.8 m/s²

s = 40 m

v = ?

Now, on applying the third equation of motion.

v² = u²+2as.

v² = 0² + 2×0.8×40

v² = 0 + 1.6 × 40

v² = 64

v = √64m/s or...

v = 8 m/s...
