Question

Starting from rest a car accelerates uniformly at a rate of
20 m/sec? for 30 seas. find its final velocity ?​

Answer 1

Answer:

5 km is the answer, please mark me brainlist answer

Answer 2

Answer:  600 m/sec

Explanation:

Starting from rest a car accelerates uniformly at a rate of

20 m/sec for 30 secs.

Given: initial velocity u = 0,

acceleration   $a = 20 ~ m/ sec^2$   [You have types wrong the unit]

time taken t = 30 sec

We have to find final velocity v.

Using the equation: v = u + at

we have, v = (0 + 20 x 30 ) m/sec = 600 m/sec.

So its final velocity is 600 m/sec.
