A1 DOUBLES ASSIGNMENT 24 PART B – Drill Ans. Ans. PROBLEM SOLVING 1. A car is moving along a straight road with uniform acceleration. The car passes a point with a speed of 12 m s-1 and another check-point with a speed of 32 m s-1. A C The distance between and is 1100 m. A C (a) Find the time, in seconds, taken by the car to move from to A C. Given that is the mid-point of B AC, (b) find, in m s-1 to 1 decimal place, the speed with which the car passes B. ANS: (a) 50 seconds (b) 24.2 ms-1 2. A particle is moving on an axis From time = 0 s to time =32 s, the particle is Ox. t t travelling with constant speed 15 m s. The particle then decelerates from 15 m s to rest in seconds. T
