which one is an object accelerating?
a)car traveling on a Straight Flat road at 50 miles per hour
b)a car traveling on a straight uphill road at 30 miles per hour
c) a car going around a circular track ata steady 100miles per hour
Please help…thank you so much!!!
Circular motion requires angular acceleration perpendicular to the direction of travel. A car going around in a circle is constantly accelerating inwards towards the center of the circle. If not for the acceleration the car would go in a straight line.
