A) 3 unit
B) - 3 unit
C) 4 unit
D) - 4 unit
Correct Answer: D
Solution :
Given, distance travelled by an object along a straight line in time t is \[3-4t+5{{t}^{2}}\] Here, the velocity \[\frac{ds}{dt}=-4+10\,t\] Hence, initial velocity will be \[{{\left| u=\frac{ds}{dt} \right|}_{t=0}}=-4\,\text{unit}\]You need to login to perform this action.
