Question

The initial velocity of an object is 10 m / s^-1 and its velocity is 3 m / s^2. So what will be the velocity of the object after 9 seconds?​

Answer 1

.852 km & 13.6 g/cm³

Answer 2

initial velocity = 10 m/s

acceleration (because the unit is m/s^2...)  = 3m/s^2

time = 9 seconds

we know that,

a = $\frac{v-u}{t}$

=> 3 = (v - 10)/9

=> 3 *9 = v - 10

=> 27+10 = v

=> 37 m/s

i hope this helps you...
