Question

the displacement of a body is given by x= 8t- 4t^2.
at which time its velocity along x axis will be zero​

Answer 1

Answer: 1

Explanation:

x=8t-4t²-------------------(1)

since velocity(v)=$\frac{dx}{dt}$

differentiating wrt to time (t) in eq 1 we get

dx/dt=8-8t

v=8-8t

as per question velocity is zero

so by putting v=0 we get time t=1
