A car starts from rest and retains the acceleration of 4m/s² in 20 second. calculate its final velocity. step by step

Car batteries are often rated in amp-hours. this rating indicates the quantity of charge that can pass through the battery before the battery's chemical energy must be restored by the car's generator or some other source. the amp-hour unit is convenient for simple calculations. for example, a 60-amp-hour battery can supply a current of 1.0 a for 60 h (or 60 a for 1.0 h) before going dead. find the energy stored in the following. (a) a 58 a-h, 10 v car battery(b) a 1.3 a-h, 1.7 v flashlight battery

You are now given an additional piece of information: it takes five complete revolutions for the turntable to speed up from 3313rpm to 45rpm. which of the following equations could you use to directly solve for the numerical value of the angular acceleration α?
