A ball accelerates uniformly at +4.0 m/s2 If the ball was initially moving a +0.20 m/s and the average velocity was +4.2 m/s, then how long will it take it to reach the final velocity?

Ineed the answer to question 1 , i’m desperate

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

Which of the following are appropriate acceleration units?
