At time t = 0 s, automobile A is traveling at a speed of 17.5 m/s along a straight road and is picking up speed with an acceleration that has a magnitude of 4.00 m/s2 as in part a of the figure. At t = 0 s, automobile B is traveling at a speed of 17.5 m/s in uniform circular motion as it negotiates a turn (part b of the figure). It has a centripetal acceleration whose magnitude is also 4.00 m/s2. Determine the speed of (a) automobile A and (b) automobile B, when t = 2.0 s.

A car of mass M = 1300 kg traveling at 45.0 km/hour enters a banked turn covered with ice. The road is banked at an angle θ, and there is no friction between the road and the car's tires as shown in (Figure 1) . Use g = 9.80 m/s2 throughout this problem. What is the radius r of the turn if θ = 20.0 ∘ (assuming the car continues in uniform circular motion around the turn)?
