1. 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 travelling?

2.The distance between mumbai to delhi is 1384. A train starts from Mumbai at 4pm and reaches delhi at 10 am the next day.What is its average speed?

3.State the 3 equations of motion. Which equation describes velocity-time relation and position -time relation?

4. A cheetah starts from rest and accelerates at 2 m/s2 for 10 seconds. Calculate the final velocity and the distance travelled?

Expert Answer:

The equation to be used is :- V2 = U2+2aS, where V and U are final and initial velocity respectively, a is acceleration and S is distance travelled.
 
hence V2 = 8×8 + 2×1×18 = 100, hence V = 10 m/s
 
only one question should be posted per post.
