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?

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

Accelaration =(v-u)/t

40-10/20m/s^2

30/20m/s^2

1.5m/s^2=accelaeration

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
