Question

If a rocket initially at rest accelerates at a rate of 50 m/s2 for one minute, its speed will be

Answer 1

`\huge\boxed{\sf v_f=3000 \ m/s}`

Step-by-step explanation:

Given Data:

Acceleration = a = 10 m/s²

Time = 1 minute × 60 = 60 seconds

Initial Velocity = Vi = 0 m/s

Required:

Final Velocity = Vf = ?

Formula:

`\displaystyle a=(v_f-v_i)/(t)`

Solution:

`50 =(v_f-0)/(60) \\\\Multiply \ 60 \ to \ both \ sides\\\\50 * 60 = v_f\\\\3000 \ m/s = v_f\\\\\boxed{v_f=3000 \ m/s}\\\\\rule[225]{225}{2}`
