Question

body starting from rest and moving with an uniform acceleration of 3 m/s²..What is its velocity after 15s?​

Answer 1

Answer:

45m/s^2

Explanation:  v=u+at

                     v= 0+3*15   = 45

Answer 2

Given:

• initial velocity = 0 m/s ...(as it started moving from rest)
• acceleration = 3 m/s^2
• time = 15 seconds

To find:

Velocity = ?

Solution:

We know Newton's first kinematic equation i.e, v = u + at

(put the values)

--> v = 0 + 3 × 15

--> v = 45 m/s

Hence the required ans is 45 m/s

Hoped this help you dear...
