Question

1. Define velocity. State the S I unit of velocity. 2. Dis nguish between uniform circular mo on and linear mo on. 3. Draw a velocity- me graph to show the following mo on. A car accelerates uniformly from rest for 5 seconds and then it travels at a steady velocity for 5 seconsds.Calculate the total distance travelled from the graph. 4. To derive the equa on of mo on graphically. 2as=v 2-u 2 . 5. Convert a speed of 54km/h into m/s. 6. A train travels the first 15 km at uniform speed of 30km/h, the next 75km at a uniform speed of 50km/h, and the last 10km at a uniform sped of 20km/h. Calculate the average speed for the en re journey. 7. An ant travels a distance of 8 cm from P to Q and then moves a distance of 6 cm at right angles to PQ. Find the resultant displacement. 8. What term is used to denote the change of velocity with me? Define the term. 9. A par cle is moving in a circular path of radius r. What is the displacement a er comple ng half a circle? 10. What does the slope of distance me graph and velocity me graph indicates? 11. What can you say about the mo on of a body if its speed- me graph is a straight line parallel to the me axis? Draw the graph. 12. A car is travelling along the road at 8 m/s. It accelerates at 1m/s2 for a distance of 18m.How fast is it then travelling? 13. A bus is moving along a straight line at 20m/s undergoes an accelera on of 4m/s2.A er 2 seconds what is its speed? 14. What is meant by retarda on? What is its S I unit? 15. A bus running at a speed of 18km/h is stopped in 2.5 seconds by applying brakes. Calculate the retarda on produced.

Answer 1

Answer:

velocity=displacement by time taken..

Explanation:

later on tell u the answer for other questions..

but this mayhelps you little

Answer 2

Answer:

it is very long question so ask one by one..............
