Question

Question 27 2 pts A car rounds a circular track at a constant speed v. If the speed of the car is reduced to v/2, the centripetal acceleration decreases by a factor of 4 increases by a factor of 4 decreases by a factor of 2. increases by a factor of 2.

Answer 1

Decreases by a factor of 4

Salution Cenniketal Acceleration If radius remains constant ac ac e² Thus foom this equation if velocity is reduced to / as a wh 4 .. So the centripetal acceleration of the can decreases by a factor of 4
