Derive an expression for average velocity and instantaneous velocity for the motion of an object in x-y plane.

### Asked by Tinuomrajankar | 6th Sep, 2021, 10:26: AM

Expert Answer:

- Acceleration is defined as the rate of change in velocity with time.

Acceleration = Change in velocity/ Time taken

Average acceleration = Total change in velocity/ Total time taken

Thus, average acceleration,

Instantaneous velocity: -It is the velocity of the particle at a given instant. The direction of instantaneous velocity is

along the tangent drawn to the curve describing the path at that instant if the body undergoes

curvilinear motion.

- the velocity of a particle moving along x axis is given by v=x2 - x, where x is metre and v in m/s what is its position when velocity is minimum
- 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?
- the motion by body is described by the equation v=at square find the distance travelled by the body in the first 2second
- a man travels on a straight road from his home to the bank with a uniform speed of 18km/h for 10s and then travels with a uniform speed of 36 km/h for next 20 s on a straight road from bank to market. the average speed of the man for the whole journey is
- Particles moves a certain distance In a staright line as follows first 1/4th at V° next 1/2th at 2v2 last 1/4 th at v0 find avg speed
- from A to B speed is v⁰. From B to C during first half speed is v1 and during last half speed is v2 . Find Average Speed From A to C
- a particle has initial velocity of 9 m/s^2 and retardation of 2m/s^2.find the distance travelled in 5 th second
- A passenger in a train with speed 72 km/h observed another train coming from the opposite direction with speed 32.4 km/h. What's the length of the second train if it crosses the passenger in 10s?
- the speed necessary to go into orbit around the earth is 8km/h.it is also necessary to travel about 200 km in order to get out of the atmosphere suppose a rocket can reach their speed after travelling 200 km under constant acceleration what could be the acceleration
