Question

What is the acceleration of the object with velocity as 50m/s and time taken is 40s

Answer 1

Answer:

Acceleration = 1.25 m/s^2

Explanation:

Since the body has started from zero velocity,

Therefore, Initial velocity (u) = 0 m/s

Given,

Final velocity (v) = 50 m/s

Acceleration (a) = ?

Time (t) = 40 secs

Since,

By first equation of motion is,

v = u + (a*t)

v-u = a * t

(v-u) /t = a

a = (50-0) /40

a = 50/40

a = 5/4

a = 1.25 m/s^2
