Question

a body has initial velocity 3m/s and its retardation is 2 m/s square . find the final velocity after 3 sec​

Answer 1

Answer:

-3m/s

Explanation:

Given--

u = 3m/s

acc. = -2m/s

To find (v) we need the equation

v=u+at

On putting the value

we get

= (3 + -2*3) m/s

=(3 + -6) m/s

= -3 m/s

hpoe it will help you

Answer 2

Given :-

The initial velocity u= 3 m/sec

Solution :-

U= 3m/s

According = -2m/s

To Find (v) we need the equation

V=U+ at

On putting the value

we get

= (3+-2*3) m/s

= (3+-6) m/s

= -3 m/s

~ -3 m/s
