Question

how to find the acceletation when intial velocity and time is given
​

Answer 1

Explanation:

HEY Mate...

From 2nd derivation....

S =ut+1/2at^2...

Plzz mark it's brainliest answer...

Answer 2

Explanation:

Acceleration is the rate of change of velocity .

If initial velocity = u

time = t

final velocity = v

Then , (v - u )/t = a

In some cases , we are just given u and t but not v .The QUESTION may say that body comes to rest , then a = -u/t

Generally , when we throw something up then we say that a body is through with initial velocity u and attains it's maximum height in t sec .

Then , a = -u /t ......

or , a = - u ^2/ 2h

....

Secondly , u can use 2 nd equation of motion
