Question

velocity of a particle moving along a straight line is given by v= t^2-3t- 4 metre per second find the velocity at the instant when no net force is applicable on particle – metre per second​

Answer 1

Answer:

hope u help this and verify the ans

and mark bainliest

Explanation:

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
