Question

21
A body moving with uniform acceleration
travels distance 12 meter in the third second
and 20 meter in fifth second. Find the velocity
after 10th second.
(1) 40 m/s
(2) 42 m/s
(3) 52 m/s
(4) 4 m/s​

Answer 1

Answer:

4 m\s option fourth

I hope it help to u

Answer 2

Answer:

1 ...40m per second is the correct answer

Explanation:

$given \\ \\ \\ \\ first \: distance \: 12m \: and \: time \: is \: 3sec \: and \: second \: distance \: is \: 20m \\ \\ \\ \\ so \: the \: average \: velocit y \: is \: total \: distance \: by \: total \: timetaken \\ \\ it \: mean \: the \: average \: velocity \: is \: 4m \: per \: second \: \\ \\ \\ \\ so \: find \: the \: velocity \: after \: 10sec \: \\ \\ \\ so \: th \: velocity \: is \: 4 \times 10 = 40m \: per \: second$
