If s=3t^2+4t+9 find velocity at t=2sec. Also find average velocity between 1sec and 4sec |
| Answer» Velocity at t=2sec is 16m/s. You just need to differentiate the distance equation with respect to time which will give you--> v=6t+4 and now just substitute the value of time that is 2 sec and this will give 16m/s. | |
