[kurosaki69]

Homework Statement

can some explain it to me, how to solve?
also can how to find instantaneous velocity?

Homework Equations

The Attempt at a Solution

 

[proton]

instantaneous acceleration is the acceleration at a given instant of time. If an object moves at constant acceleration, its instantaneous acceleration is the same for all instances of time.

to solve for it, take the derivative of velocity as a function of time. Then plugin the value of t, where t is the instant of time you want to find the acceleration for
