An object is moving due south at 16 m/s, when a force accelerates it at 4m/s in a southerly direction. how long will it take for the object to reach a velocity of 48 m/s south. me out.

Time taken to accelerate to 48 m/s =  8 seconds

Explanation:

Initially the object is moving south at =

So, initial velocity of the object =

Acceleration caused by the force = 4

Final velocity towards south =

Using equation of motions:

where

final velocity

initial velocity

acceleration

time

Plugging in values.

Subtracting both sides by 16

Dividing both side by 4.

∴

Time taken to accelerate to 48 m/s =  8 seconds

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.)
