A car starts at Point A at t = 0 s with a speed vo = 18 km/h. Its speed increases at a constant rate to Point C, where its velocity is vc = 144 km/h. The curved portion has a radius, r= 148 m, and the distance between Point B and Point C is, x = 105 m. Determine the car's speed at Point B. Use one decimal place in your answer. HInt: Make sure to convert all quantities to the correct units before performing calculations!
