Q1.A race car starts from rest on a circular track of radius 453 m. The car's speed increases at the constant rate of 0.800 m/s2. At the point where the magnitudes of the centripetal and tangential accelerations are equal, discover the following-
(a.) speed of the race car
(b.) distance travelled
(c.) elapsed time
Q2. Three deer, A, B, and C, are grazing in a field. Deer B located 65 m from dear A at an angle of 52° north of west. Deer C is located 75° north of east relative to dear A. The distance between deer B and C is 92 m. What is distance between deer A and C?
