Question

The displacement of a particle moving along X-axis is given by X=67-3t" meter. When
will the velocity of the particle is zero?​

Answer 1

Explanation:

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
