Velocity in terms of x QUESTION (1 Viewer)

[posh bitch]

i have uploaded a pic of a question from the margaret grove textbook

just one question. it states that the particle is INITIALLY (t=0) at rest (v=0) to the right of the origin (x=5)

then it states that v=4x

but when t=0, x=5
hence, v=4x5 which is 20 and NOT 0

so it cant be at rest ?

help please, i want to understand this question

Did u find an equation of v(t)? (velocity versus time)

isnt that just the generic equation? you need to use it to answer the question - those are just initial conditions
