- What is Velocity?
- A cyclist covers a distance of 50 m in 10 s. Calculate the speed of the cyclist in I m/s (ii) km/h
- define velocity
- An object moves 9 m in first 3 sec, 11 m in next 3 sec, and 7 in last 3 sec. What is its average speed?
- a body travels along a circular path of radius 70 me after travelling half a revolution in 20 seconds find the average speed and average velocity
- an object level 18 metre in 4 seconds and next 18 metre into second calculate average speed of the object
- A body is moving with a velocity of 10 m/s .if the motion is uniform what will be the velocity after 10s
- an aeroplane files 200km with a uniform speed of 300 km per hour and then another 200km with a uniform speed of 240 km per hour calculate the average speed of aeroplane
- Two trains A and B start moving at the same time. The distance travelled by them in given intervals of time are given below. Plot the Distance- time graph for the motion of two trains. State which train has uniform motion and which train has non- Uniform motion. Also Plot Speed- time graph after calculating the speed of the two trains at different time intervals.
- The distance between Delhi and Agra is 200 km A train travels the first hundred kilometres at a speed of 50 km per hour how fast must the train travel the next hundred kilometres so as to average 70 km per hour for the whole journey In this why can't we use the formula Average speed = initial speed + final speed / 2
