Question 13 A car drives on a curved section of the road, initially going due South at 15 m/s, then going due West at 13 m/s. If this turn takes 1.4 seconds to complete, what is the magnitude of the acceleration (in m/s²) during that turn? Round to the nearest hundredth (0.01).

When the motorcyclist is at A, he increases his speed along the vertical circular path at the rate of v (0.3t) ft/s², where t is in seconds. Take p = 350 ft. (Figure 1) Figure 60° p 1 of 1 Part A If he starts from rest at A, determine the magnitude of his velocity when he reaches B.

Problem 8: Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of v= 4.4 cm/year. What distance d, in meters, does the plate move in 1.6 seconds at this speed?

t path A in the figure. A city block is asquare of l = 105 m on each side. What is the total distance traveled on path A in meters? What is the magnitude of the displacement in meters? What is the angle of displacement, in degrees, measured east of north?
