Question

Brainliest for correct answer :)
An object travelling for 20 seconds initially travels at 10ms-1 and increases its speed to 40ms-1 what is its acceleration?

Answer 1

Answer:

Acceleration a =-1.75 m/s²

Explanation:

Given:

Initial speed u = 24 m/s

Final speed v = 10 m/s

Time taken t = 8 sec

Find:

Acceleration a

Computation:

a = (v-u)/t

a = (10-24)/8

a = -14 / 8

Acceleration a =-1.75 m/s²
