a1. A bus starting from rest has an acceleration of 0.1 m/s2. What will be the velocit of the bus after 20 seconds? [Ans: 2 m Two vehicles are moving in the same direction. The velocity of the first vehicle i 8 m/s and the velocity of the second vehicle is 5 m/s. Find their relative velocit What will be the relative velocity if they move in the opposite directions? [Ans: 3 m/s, 13 m g. A car is travelling in the velocity of 20 m/s. After 30 sec it covers a distance o 1200 m. Calculate the acceleration of the car and the final velocity of the car. [Ans: 1.14 m/s2, 54.2 A truck starts to move from rest. If it gains the acceleration of 3 m/s2 in 5 sec, calculate the final velocity and distance covered by the truck. [Ans: 15 m/s, 37.5 iple Choice Questions
