a car travels along a horizontal circular curved


A car travels along a horizontal circular curved road that has a radius of 600 m. If the speed is uniformly increased at a rate of 2000 km>h2, determine the magnitude of the acceleration at the instant the speed of the car is 60 km>h.

Ans) a2=(ar)2+(at)2

a2=v2/r+(2000km/hr2)2

a2=36000000+4000000

a=6.32*103
