Question

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

Answer 1

Answer:

X = 4t

2

+ 3t + 7

V =

dt

dx

= instantaneous velocity

V = 8t + 3

at t = 2

v = 19 m/s

a =

dt

dv

instantaneous accelesation

a= 8 (constant)

at t = 2

a=8 m/s
