Question

An object is moving with a speed of 15 mls. It
is ithen given van accelaration of 5 m/s². Find
uts velocity after 10 seconds​

Answer 1

Answer:

u=15m/s  ,a=5m/s  ,t=10s  ,v=?

Solution:

∵a= v-u

       t

5= v-15

     10

50 +15=v

v= 65 m/s

HOPE THIS MAY HELP YOU!!

Answer 2

Answer:

Explanation:

Given,

Initial velocity of the object, u = 15 m/s

Acceleration of the object, a = 5 m/s²

Time taken by object, v = 10 seconds

To Find,

Final velocity of the object, v

Formula to be used,

1st equation of the motion,

v = u + at

Solution,

Putting all the values, we get

v = u + at

⇒ v = 15 + 5 × 10

⇒ v = 15 + 50

⇒ v = 65 m/s

Hence. the final velocity of the object is 65 m/s.
