A car travels along a horizontal circular curved road that, Ask an Expert

Academics

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=(a_r)²+(a_t)²

a²=v²/r+(2000km/hr²)²

a²=36000000+4000000

a=6.32*10³
