A car travels along a horizontal circular curvedroad that has a radius of 600 m. If the speed is uniformlyincreased at a rate of 2000 km>h2, determine the magnitudeof the acceleration at the instant the speed of the car is60 km>h.
a2 = (v2/r)2 + aT = (3600/0.6)2 + (2000)2 = (6000)2 + (2000)2 = 40*106
a≈6.32*103 km/h2
a2=(ar)2+(at)2
a2=v2/r+(2000km/hr2)2
a2=36000000+4000000
a=6.32*103
