| Vidushi pundir asks : at t=0, a particle at origin has a velocity of 15m/s at 37 degree above the horizontal X axis.At t=5s, it is at x=20m, y=35m and its velocity is 30m/s at 53 degree above the horizontal.find its avg acceleration |
| Alia kapoor asks : What is meant by instantaneous speed and instantaneous acceleration ? Explain with example . |
| Prakhar srivastava asks : v=k(x)^1/2.. here v= velocity, x=distance. what will be the acceleration-time graph? how do you get it. |
